| The Tier 4 PzKpfw IV tank is considered if not the best, then definitely the most versatile low tier medium in the game. Fast and agile with the Standard turn, and heavily armored once upgraded with the Schmalturm, PzKpfw IV is one of the few lower tier tanks that can't be ignored on the battlefield even by the highest tier tanks. Placed at the very important part of the German tech tree, PzKpfw IV can be played in many different roles. As a long range sniper when mounted with long 75 gun, or as a close combat knife fighter when fitted with the short 105 mm marshmallow gun. | The Tier 4 PzKpfw IV tank is considered if not the best, then definitely the most versatile low tier medium in the game.

| Designed as an infantry-support tank, the Panzer IV was not originally intended to engage enemy armor, that role was presumed for the lighter Panzer III. However, after shocking expiriences when facing T-34 and KV tanks on the eastern front, the Panzer IV soon assumed the anti tank role of its increasingly obsolescent cousin. The most widely manufactured and deployed German tank of the Second World War, the Panzer IV was used as the base for many other fighting vehicles, including tank destroyers and self-propelled guns. Robust and reliable, and relativly simple to produce it saw service in all combat theaters involving Germany, and has the distinction of being the only German tank to remain in continuous production throughout the war, with over 8,800 produced between 1936 and 1945. Upgrades and design modifications, often made in response to the appearance of new Allied designs, extended its service life. Generally these involved increasing the Panzer IV's armor protection or upgrading its weapons, although during the last months of the war with Germany's pressing need for rapid replacement of losses, design changes also included retrograde measures to simplify and speed manufacture. | Designed as an infantry-support tank, the Panzer IV was not originally intended to engage enemy armor, that role was presumed for the lighter Panzer III.

| In concept, it was intended to be a support tank for use against enemy anti-tank guns and fortifications. Ideally, the tank battalions of a panzer division were each to have three medium companies of Panzer IIIs and one heavy company of Panzer IVs. On 11 January 1934, the German army highly influenced by Heintz Guderian wrote the specifications for a "medium tractor", and issued them to a number of defense companies. To support the Panzer III, which would be armed with a 37-millimetre anti-tank gun, the new vehicle would have a short barrelled 75-millimetre howitzer as its main gun, and was allotted a weight limit of 24 tonnes. Development was carried out under the name Begleitwagen ("accompanying vehicle"), or BW, to disguise its actual purpose and hide from the Treaty of Versailles limitations. MAN, Krupp, and Rheinmetall-Borsig each developed prototypes, with Krupp's selected for further development. | In concept, it was intended to be a support tank for use against enemy anti-tank guns and fortifications.

| The chassis had originally been designed with a six-wheeled interleaved suspension, but the German Army amended this to a torsion bar system. Permitting greater vertical deflection of the roadwheels, this was intended to improve performance and crew comfort both on- and off-road. However, due to the urgent requirement for the new tank, neither proposal was adopted, and Krupp instead equipped it with a leaf spring double-bogie suspension. | The chassis had originally been designed with a six-wheeled interleaved suspension, but the German Army amended this to a torsion bar system.

| The prototype required a crew of five men; the hull contained the engine bay to the rear, with the driver and radio operator, who doubled as the hull machine gunner, seated at the front-left and front-right, respectively. In the turret, the tank commander sat beneath his roof hatch, while the gunner was situated to the left of the gun breech and the loader to the right. The turret was offset 66.5 mm to the left of the chassis center line, while the engine was moved 152.4 mm to the right. This allowed the torque shaft to clear the rotary base junction, which provided electrical power to turn the turret, while connecting to the transmission box mounted in the hull between the driver and radio operator. Due to the asymmetric layout, the right side of the tank contained the bulk of its stowage volume, which was taken up by ready-use ammunition lockers. Production began in 1936 at Krupp-Grusonwerke AG's factory at Magdeburg. | The prototype required a crew of five men; the hull contained the engine bay to the rear, with the driver and radio operator, who doubled as the hull machine gunner, seated at the front-left and front-right, respectively.

| ? | The first mass-produced version of the Panzer IV was the Ausführung, A in 1936. It was powered by Maybach's HL 108TR, producing 250 PS (183.87 kW), and used the SGR 75 transmission with five forward gears and one reverse, achieving a maximum road speed of 31 kilometres per hour. As main armament, the vehicle mounted the Kampfwagenkanone 37 L/24 (KwK 37 L/24) 75 mm tank gun, which was a low-velocity gun designed to mainly fire high-explosive shells.[13] Against armored targets, firing armor-piercing rounds at the velocity of 430 metres per second the KwK 37 could penetrate 43 millimetres of armor, inclined at 30 degrees, at ranges of up to 700 metres. A 7.92 mm MG 34 machine gun was mounted coaxially with the main gun in the turret, while a second machine gun of the same type was mounted in the front plate of the hull. The Ausf. A was protected by 14.5 mm of steel armor on the front plate of the chassis, and 20 mm (0.79 in) on the turret. This was capable only of stopping artillery fragments, small-arms fire, and light anti-tank projectiles. Variant from Ausf. B to Ausf F1 featured mostly armor improvements, new engine and suspenension witch combined with the wider tracks increased the weight to 22.3 tons. Main armament was still KwK 37 L/24 althow tests with the 5 cm PaK 38 L/60 were succesfull and the new gun was to be implemented in the next version. However, shocking expiriences against Soviet T-34 and KV tanks caused this idea to be dropped, and a new 75 mm gun was to be implemented.. Because the recoil length of the existing 7.5 cm PaK 40 L/46 gun was too long for the tank's turret, the recoil mechanism and chamber were shortened. [[image:PzKpfw IV Ausf G.JPG|thumb|280px|right|PzKpfw IV Ausf G]]This resulted in the 75-millimetre KwK 40 L/43. When firing an armor-piercing shot, the gun's muzzle velocity was increased from 430 m/s to 990 m/s. Initially, the gun was mounted with a single-chamber, ball-shaped muzzle brake, which provided just under 50% of the recoil system's braking ability. Firing the Panzergranate 39, the KwK 40 L/43 could penetrate 77 mm of steel armor at a range of 1,830 m. The Ausf. F tanks that received the new, longer, KwK 40 L/43 gun were named Ausf. F2. The tank increased in weight to 23.6 tonnes. One hundred and seventy-five Ausf. F2s were produced from March 1942 to July 1942.Three months after beginning production, the Panzer IV. Ausf. F2 was renamed Ausf. G. There was little to no difference between the F2 and early G models. | + | The first mass-produced version of the Panzer IV was the Ausführung, A in 1936.

| ? | During its production run from May 1942 to June 1943, the Panzer IV Ausf. G went through further modifications, including another armor upgrade. Given that the tank was reaching its viable limit, to avoid a corresponding weight increase, the appliqué 20-millimetre steel plates were removed from its side armor, which instead had its base thickness increased to 30 millimetres. The weight saved was transferred to the front, which had a 30-millimetre face-hardened appliqué steel plate welded (later bolted) to the glacis—in total, frontal armor was now 80 mm thick. This decision to increase frontal armor was favorably received according to troop reports on November 8, 1942, despite technical problems of driving system due to added weight. At this point, it was decided that 50% of Panzer IV productions would be fitted with 30 mm thick additional armor plates. Subsequently on January 5, 1943, Hitler decided to make all Panzer IV with 80 mm frontal armor. To simplify production, the vision ports on either side of the turret and on the right turret front were removed, while a rack for two spare road wheels was installed on the track guard on the left side of the hull. Complementing this, brackets for seven spare track links were added to the glacis plate. [[image:PzKpfw IV Ausf H without armor skrits.jpg|thumb|280px|left|PzKpfw IV Ausf H]] | + | ||

| For operation in high temperatures, the engine's ventilation was improved by creating slits over the engine deck to the rear of the chassis, and cold weather performance was boosted by adding a device to heat the engine's coolant, as well as a starter fluid injector. A new light replaced the original headlight, and the signal port on the turret was removed. On March 19, 1943, the first Panzer IV with Schurzen skirts on its sides and turret was exhibited. The double hatch for the commander's cupola was replaced by a single round hatch from very late model Ausf. G. and the cupola was up-armored as well. In April 1943, the KwK 40 L/43 was replaced by the longer 75-millimetre KwK 40 L/48 gun, with a redesigned multi-baffle muzzle brake with improved recoil efficiency. The next version, the Ausf. H, began production in April 1943. This variant saw the integrity of the glacis armor improved by manufacturing it as a single 80-millimetre plate. To prevent adhesion of magnetic anti-tank mines, which the Germans feared would be used in large numbers by the Allies, Zimmerit paste was added to all the vertical surfaces of the tank's armor. The vehicle's side and turret were further protected by the addition of 5-millimetre side-skirts and 8-millimetre turret skirts. During the Ausf. H's production run its rubber-tired return rollers were replaced with cast steel; the hull was fitted with triangular supports for the easily-damaged side-skirts. There modifications meant that the tank's weight jumped to 25 tonnes, reducing its speed, a situation not improved by the decision to adopt the Panzer III's six-speed SSG 77 transmission, which was inferior to that of earlier-model Panzer IVs. | For operation in high temperatures, the engine's ventilation was improved by creating slits over the engine deck to the rear of the chassis, and cold weather performance was boosted by adding a device to heat the engine's coolant, as well as a starter fluid injector.

| The Panzer IV was the only German tank to remain in both production and combat throughout World War II, and measured over the entire war it comprised 30% of the Wehrmacht's total tank strength. Although in service by early 1939, in time for the occupation of Czechoslovakia,[60] at the start of the war the majority of German armor was made up of obsolete Panzer Is and Panzer IIs. When Germany invaded Poland on 1 September 1939 the modern Panzer III and IV vehicles amounted to less than 10% of Germany's armored strength. Although the Polish army possessed less than 200 tanks capable of penetrating the German light tanks, Polish anti-tank guns proved more of a threat, reinforcing German faith in the value of the close-support Panzer IV. Despite increasing production of the medium Panzer IIIs and IVs prior to the German invasion of France on 10 May 1940, the majority of German tanks were still light types. According to Heinz Guderian, the Wehrmacht invaded France with 523 Panzer Is, 955 Panzer IIs, 349 Panzer IIIs, 278 Panzer IVs, 106 Panzer 35(t)s and 228 Panzer 38(t)s. Through the use of tactical radios and superior tactics, the Germans were able to outmaneuver and defeat French and British armor. However, Panzer IVs armed with the KwK 37 L/24 75-millimetre tank gun found it difficult to engage French tanks such as Somua S35 and Char B1, and British Matilda Mk II was even more formidable opponent. | The Panzer IV was the only German tank to remain in both production and combat throughout World War II, and measured over the entire war it comprised 30% of the Wehrmacht's total tank strength.

| Although the Panzer IV was deployed to North Africa with the German Afrika Korps, until the longer gun variant began production, the tank was outperformed by the Panzer III with respect to armor penetration. Both the Panzer III and IV had difficulty in penetrating the British Matilda II's thick armor, while the Matilda's 40-mm QF 2 pounder gun could knock out either German tank; its major disadvantage was its low speed. By August 1942, Rommel had only received 27 Panzer IV Ausf. F2s, armed with the L/43 gun, which he deployed to spearhead his armored offensives. The longer gun could penetrate all American and British tanks in theater at ranges of up to 1,500 m. Although more of these tanks arrived in North Africa between August and October 1942, their numbers were insignificant compared to the amount of matériel shipped to British forces.The Panzer IV also took part in the invasion of Yugoslavia and the invasion of Greece in early 1941.[76] | Although the Panzer IV was deployed to North Africa with the German Afrika Korps, until the longer gun variant began production, the tank was outperformed by the Panzer III with respect to armor penetration.

| With the launching of Operation Barbarossa on 22 June 1941, the unanticipated appearance of the KV-1 and T-34 tanks prompted an upgrade of the Panzer IV's 75 mm gun to a longer, high-velocity 75 mm gun suitable for antitank use. This meant that it could now penetrate the T-34 at ranges of up to 1,200 m at any angle. The 75 mm KwK 40 L/43 gun on the Panzer IV could penetrate a T-34 at a variety of impact angles beyond 1,000 m range and up to 1,600 m Shipment of the first model to mount the new gun, the Ausf. F2, began in spring 1942, and by the summer offensive there were around 135 Panzer IVs with the L/43 tank gun available. At the time, these were the only German tanks that could defeat the Soviet T-34 or KV-1. They played a crucial role in the events that unfolded between June 1942 and March 1943, and the Panzer IV became the mainstay of the German panzer divisions. Although in service by late September 1942, the Tiger I was not yet numerous enough to make an impact and suffered from serious teething problems, while the Panther was not delivered to German units in the Soviet Union until May 1943. The extent of German reliance on the Panzer IV during this period is reflected by their losses; 502 were destroyed on the Eastern Front in 1942. | With the launching of Operation Barbarossa on 22 June 1941, the unanticipated appearance of the KV-1 and T-34 tanks prompted an upgrade of the Panzer IV's 75 mm gun to a longer, high-velocity 75 mm gun suitable for antitank use.

| ? | The Panzer IV continued to play an important role during operations in 1943, including at the Battle of Kursk. Newer types such as the Panther were still experiencing crippling reliability problems that restricted their combat efficiency, so much of the effort fell to the 841 Panzer IVs that took part in the battle. Throughout 1943, the German army lost 2,352 Panzer IVs on the Eastern Front; some divisions were reduced to 12–18 tanks by the end of the year. In 1944, a further 2,643 Panzer IVs were destroyed, and such losses were becoming increasingly difficult to replace. By the last year of the war, the Panzer IV was outclassed by the upgraded T-34-85, which had an 85 mm gun, and other late-model Soviet tanks such as the 122 mm armed IS-2 heavy tank.[88] Nevertheless, due to a shortage of replacement Panther tanks, the Panzer IV continued to form the core of Germany's armored divisions, including elite units such as the II SS Panzer Corps, through 1944. In January 1945, 287 Panzer IVs were lost on the Eastern Front. It is estimated that combat against Soviet forces accounted for 6,153 Panzer IVs, or about 75% of all Panzer IV losses during the war.

| + | The Panzer IV continued to play an important role during operations in 1943, including at the Battle of Kursk. Newer types such as the Panther were still experiencing crippling reliability problems that restricted their combat efficiency, so much of the effort fell to the 841 Panzer IVs that took part in the battle. Throughout 1943, the German army lost 2,352 Panzer IVs on the Eastern Front; some divisions were reduced to 12–18 tanks by the end of the year. In 1944, a further 2,643 Panzer IVs were destroyed, and such losses were becoming increasingly difficult to replace.

| Panzer IVs comprised around half of the available German tank strength on the Western Front prior to the Allied invasion of Normandy on June 6, 1944. Most of the 11 panzer divisions that saw action in Normandy initially contained an armored regiment of one battalion of Panzer IVs and another of Panthers, for a total of around 160 tanks, although Waffen-SS panzer divisions were generally larger and better-equipped than their Heer counterparts. Regular upgrades to the Panzer IV had helped to maintain its reputation as a formidable opponent. Despite overwhelming Allied air superiority, the Norman bocage countryside in the US sector heavily favored defense, and German tanks and anti-tank guns inflicted horrendous casualties on Allied armor during the Normandy campaign. On the offensive, however, the Panzer IVs, Panthers and other armored vehicles proved equally vulnerable in the bocage, and counter-attacks rapidly stalled in the face of infantry-held anti-tank weapons, tank destroyers and anti-tank guns, as well as the ubiquitous fighter bomber aircraft. That the terrain was highly unsuitable for tanks was illustrated by the constant damage suffered to the side-skirts of the Ausf. H's; essential for defence against shaped charge anti-tank weapons such as the British PIAT, all German armored units were "exasperated" by the way these were torn off during movement through the dense orchards and hedgerows. | Panzer IVs comprised around half of the available German tank strength on the Western Front prior to the Allied invasion of Normandy on June 6, 1944.

| During the winter of 1944–45, the Panzer IV was one of the most widely used tanks in the Ardennes offensive, where further heavy losses—as often due to fuel shortages as to enemy action—impaired major German armored operations in the West thereafter. The Panzer IVs that took part were survivors of the battles in France between June and September 1944, with around 260 additional Panzer IV Ausf.

Before you get into combat, you should have your tank fully loaded with ammunition; if your tank is loaded with too few rounds for the match, a warning will pop up. Be careful not to click past it. The amount of ammunition of each tank can carry depends on the gun caliber and the turret, which is listed on each tank's page. The ammunition you choose will affect your combat performance. Below are brief descriptions of each shell type in the game. As of patch 0.8.1, premium ammo can optionally be purchased for credits at the standard gold-to-credit conversion rate of 1:400. In other words, a shell that costs 10 gold will cost 4000 credits.
Shell Types
Armor Piercing (AP) Shell
This shell does the full damage listed on the gun specifications if it penetrates the enemy's armor. However, if the shell doesn't penetrate the target, it will bounce and do no damage whatsoever. It can also damage tank modules and crew if it hits at the right spot. AP shells are subject to normalization, usually mitigating 5 degrees of armor sloping, and lose some penetration value over distance.
AP shells normally cost credits; however there is an AP round type, used by Soviet artillery armed with the 152 mm BR-2 gun, that must be purchased with gold and one more for Japanese tier 6-7 medium tanks.
Armor Piercing Composite Rigid (APCR) Shell
This type of ammunition has the highest penetration value, but the damage value is the same as an AP shell. It is subject to normalization, although it only normalizes by 2 degrees. It still has the AP shell characteristics, with slight twists. APCR has a higher muzzle velocity than AP, meaning a shell leaves your gun at a higher speed (resulting in less "leading" of distant moving targets), however APCR also loses more penetration value over the same distance as AP. Generally speaking, low caliber guns such as a 57mm gun will lose penetration at a much faster rate than high caliber guns such as a 120mm gun. Nevertheless, the APCR used by most medium and high tier guns will still have more penetration than standard AP at longer ranges.
APCR shells normally cost gold. However, 7.5 made APCR shells the standard ammunition used by the new tier 10 medium tanks. Additionally, 8.2 made APCR shells the standard ammunition used by the 76 mm Gun T185 cannon, which can be mounted on the T71 American light tank, and the T69 American medium tank. They cannot use AP ammo at all, and instead can purchase this ammo using credits rather than gold. Tanks whose guns default to APCR are also not subject to the same penetration loss over distance as premium APCR, but still have the higher muzzle velocity.
High Explosive (HE) Shell
This shell has the highest damage value among all the shell types in the game, but also has a very low penetration value. These rounds have a very small splash damage area. It doesn't need to penetrate to damage the target, but the damage drops off quickly as the difference between the target's armor and the shell's penetration value increases. If it manages to penetrate the armor, it will explode inside the tank for the full damage listed in the specifications, plus HE deals additional damage to multiple internal modules and/or crew, depending on how high the HE damage value is. HE shells typically have a maximum damage value 25% higher than AP shells, rounded to the first significant figure.
Premium High Explosive (HE) Shell
Found in some SPG guns, it has no significant difference to its HE counterpart other than a larger splash-damage radius, which can be very useful for hitting tanks just behind cover that can not be hit directly. Rounds with this icon cost gold or the equivalent in silver.
High Explosive Anti-Tank (HEAT) Shell
This is the Premium ammunition for most SPG-class, tank howitzer, and many high tier tank guns. It carries a higher penetration value than AP, but unlike AP and APCR, is not subject to normalization, and therefore must penetrate the effective armor value at the given impact angle, meaning HEAT will have trouble with very thick, sloped armor more than AP and APCR. However, also unlike AP and APCR, HEAT does not lose penetration value over distance.
High Explosive Squash Head (HESH) Shell
This is a specific type of shell that only some British tanks can use.
FAQ: When should I use AP or HE?
The general rule of thumb is; use AP on your own tier and below and HE for tanks higher than you, but this depends upon your gun: some are designed to use HE. Guns like the KV-2's 152 mm M-10 gun use a large caliber round, but have a short barrel length. The large caliber of the shell is substantial and carries a generous amount of explosive-compound within, thus causing more damage. The drawback is the shell leaving the gun will have a relatively low velocity because of the short barrel length and thus, low armor-piercing capability. When you factor in the poor accuracy and range, it's simply a waste to use AP shells with this type of gun and HE should be used exclusively. It is also highly recommended to use HE when attempting to reset a cap. You do not need to be as accurate with HE as a hit anywhere on an enemy tank will most likely cause even a slight amount of damage, and any damage, even if it's only a single hitpoint's worth or damaging a module, is enough to reset a tank's acquired cap points to 0. Even a near miss with HE could cause some module damage via splash. Since 8.1, gold ammo can now be bought with credits/silver. In most cases, APCR and HEAT will be much more effective at dealing with higher tier tanks than HE, which will most likely only deal very minor damage and serve only to tickle higher tier tanks with thick armor. With APCR and HEAT, you will most likely be able to abuse weakspots your gun would otherwise need extreme angles to penetrate.
Try experimenting with different ammunition to see what your gun's capabilities are on certain tanks.
When mounting tier 6 guns and higher, you should consider using AP and APCR/HEAT more frequently, as these guns have enough penetration power to damage most tanks if you know which tank and what part of the tank you should aim for.
