The M103 is an American tier 9 heavy tank.

The fully upgraded 120mm cannon is a fantastic gun, with great accuracy, and very high penetration. While it lacks alpha damage compared to the IS-8 or E-75, the gun's reload speed makes up for its lack of damage. The M103's oddly shaped hull and well-sloped turret can make this tank a bit tricky to fight, especially at long ranges; however, this tank suffers from having very weak sides and rear armor. When fighting this tank from the front, make sure you try and hit the lower armor plating as hitting the upper hull will most likely bounce. If you can only see the turret aim for the large cupola on the top of the tank for easy penetrations. The speed and maneuverability of this tank are quite good, so it's able to keep up with the rest of the team and provide excellent fire support when needed, and is able to turn its frontal hull towards the enemy quickly to reduce damage taken from incoming fire.

Player Opinion

Pros and Cons

Pros:


  • Highly sloped frontal armor and strong mantlet.
  • Good accuracy, aim time, penetration, and rate of fire on top 120mm.
  • Large tracks can absorb most shells when sidescraping


Cons:


  • Ammo rack is located on the sides of the hull and is easily damaged even from the front.
  • Turret cheeks and cupola are weak. Not a hull-down monster like T29 or T32.
  • Highly dependent on armor angles and so does not manage well against multiple foes (more so than most heavies)


Performance

Mobility, penetration, and rate of fire are this tank's strongest attributes, it is recommended to stay with other tanks when advancing, as its lack of overall armor makes it easy to damage. Stay artillery safe whenever you are not in motion, as artillery often will target hulldown tanks which otherwise would be hard to kill. Also avoid exposing your hull as the glacis plate is extremely easy to hit and penetrate. The turret ring, while hard to hit, is also easy to damage.


Early Research

  • Players should first seek to upgrade to the 120mm, as the stock 105mm's low pen and accuracy is vastly inadequate when fighting other tier 9s and 10s.
  • The next upgrade should be the turret, which will give the M103 a badly needed increase in durability and boost the rate of fire as well.
  • Next you should get the engine, as it gives the tank much better mobility.
  • After that you can decide if you want to get the top 120mm gun or to save the 60,000 XP for the T110E5 to get it sooner. The 120mm slightly upgrades rate of fire, penetration, aim time, and accuracy.
  • The radio does not have priority but it is relatively cheap to research.
  • The stock tracks allow mounting all upgraded modules, so you can wait to upgrade these if you prefer.


Historical Info

The M103 heavy tank served the United States Army and the US Marines during the Cold War. Until the development of the M1 Abrams in the mid-1970s, it was the heaviest and most heavily armed tank in US service. The M103 was manufactured at the Detroit Arsenal Tank Plant and the first units were accepted in 1957. The last M103s were withdrawn from service in 1974.

Design and Development

Like the contemporary British Conqueror tank, the M103 was designed to counter Soviet heavies such as the Josef Stalin tank or the T-10 if a conventional World War III broke out. Its long-ranged 120 mm cannon was designed to hit enemy tanks at extreme distances, but it was never used in combat. In 1953-1954 a series of 300 tanks, initially designated T43E1, were built by Chrysler at the Newark plant. Testing was unsatisfactory, and the tanks were all stored in August 1955. Only after recommending improvements, on 26 April 1956 the tank was standardized as the M103 Heavy Tank. Of the 300 T43E1s built, 80 went to the US Army (74 of which were rebuilt to M103 standard), and 220 were accepted by the US Marine Corps, to be used as infantry support, rebuilt to improved M103A1, then M103A2 standards. The successive versions of the M103 shared many components with the M47 and M48 Patton tanks and the M60, which, with the exception of the M60 (a main battle tank) were all considered 90 mm gun (medium) tanks. Tracks, rollers and suspension elements were the same, with some modification to take into account the greater weight. The engine and transmission were never modified enough to give the extra power needed for the greater weight of the M103, and as a result, the tank was relatively underpowered and the drive systems were fragile. The turret of the M103 was larger than that of the M48 or the M60 to make room for the huge 120 mm gun and the two loaders assigned to it, in addition to the gunner and the commander. The driver sat in the hull. The gun was capable of elevation from +15 to -8 degrees. The armor is made from welded rolled and cast homogeneous steel of varying thickness.

  • Hull front: 100–130 mm (4.0–5.3 in)
  • Hull side: 76 mm (3.1 in)
  • Hull top: 25 mm (1 in)
  • Turret mantlet: 250 mm (10.2 in)
  • Turret front: 180 mm (7.3 in)
  • Turret side: 76 mm (3.1 in)
  • Turret top: 38 mm (1.5 in)

Service

In Europe, the US Army fielded only one battalion of heavy tanks, from January 1958, originally assigned to the 899th Armor, later redesignated the 2/33rd Armor. The US Army heavy armor battalion, in contrast to other armor units, was organized into four tank companies, composed of six platoons each, of which each platoon contained three M103's, for a total of 18 tanks per company. Standard US Army armor battalions at the time had three companies per battalion, each with three five-tank platoons, with 17 tanks per company (two tanks were in headquarters platoon). The US Marine Corps assigned one M103 company to each of its 3 Marine tank battalions, including its Marine reserve units. While the US Army deactivated its heavy armor units with the reception of the new M60 series main battle tanks in 1963, the remaining M103s stayed within the US Marine Corps inventory until they began receiving the M60 series MBT. With the disappearance of the heavy tank from US forces came the full acceptance of the main battle tank in 1960 for the US Army, and 1973 for the US Marine Corps. Although the 21st century's M1 Abrams MBT utilizes the same caliber of main gun, the 120 mm, the M103's cannon was a rifled gun firing a fixed round, ejecting a lengthy brass shell casing (34.69 inches in length for the armor-piercing rounds). The M1 tank's 120 mm main gun is a smooth bore (no rifling) firing a semi-caseless round, ejecting only a back cap of the original loaded round; the bulk of the 120 mm shell's casing is consumed during firing. Ammunition fired by the M103's M58 cannon included:

  • APBC-T M358 Shot
  • HEAT-T M469 Shell
  • HE-T M356 Shell
  • TP-T M359E2 Shot
