[Client Values; Actual values in
Specifically, the mismatch in crew values caused by commander's 10% crew skill bonus. Outside of a crew of 1 commander only, 100% crew is a fiction. The client values, given for 100% crew, will normally be taken into battle with 110% crew skill members aside from specific functions, causing their actual performance to deviate from the expected client value. These differences are taken into account in tooltip boxes.

AnnoA57_M8A1.png

130000

The M8A1 is an American tier 4 turreted tank destroyer.

Developed in 1941 through 1942 on the basis of the M5 Stuart light tank. This SPG is an example of the successful use of an outdated chassis. The vehicle was equipped with a 75 mm short-barrel howitzer; however, attempts were made to fit a 75 mm tank gun into a modernized turret.

The M8A1 is very mobile, which, when combined with its good DPM, absolves the con of low armor. Once the crew reaches 100% in Camouflage, the M8A1 is difficult to detect. It's meant for support. A forward or close combat position, unless fully and well thought out, will result in a quick return to the garage. Although the 76 mm AT Gun M7 L/50 is a better money maker than the 57 mm, the 57 mm is superior in battle performance due to its greater penetration and higher DPM.

The M8A1 leads to the T67.

Player Opinion

Pros and Cons

Pros:


  • Fully traversable turret
  • Good mobility
  • Good view range
  • Good signal range
  • Good penetration


Cons:


  • Open topped turret makes it vulnerable to arty & HE shells
  • Weak armor; only protects against small-caliber machine guns (i.e. Pz 1c)
  • Relatively low hull traverse speed
  • Low turret traverse speed
  • Lacks the acceleration & view range to be an active scout: but good enough for passive scouting.


Performance

This little tank actually has quite a bit going for it. A turret, speed, small profile and an excellent gun. The 57mm gun is a good all rounder, making up for its slightly low alpha with a very high rate of fire. The long 75mm L/50 gun is also a good choice as well, as its much greater alpha allows a more shoot-and-scoot play style suited to it. Both choices are entirely viable, depending on the preferred play style.

Speed, and a turret give this tank added flexibility, compared to similar tiered tank destroyers. Additionally, it can be quite difficult to spot, especially if you have the Camouflage skill and/or a camouflage net. The M8A1 belongs in a supporting role, whittling down opponents who don't know any better, or those that simply can't see you.

This tank in considered by many as a "pocket Hellcat" and looks and plays similarly to its tier 6 counterpart. Additionally, due to the high skill requirement (no armor to speak of while being very fast and stealthy and not possessing a giant gun), the M8A1 doesn't have the same reputation that a Hetzer does but is arguably a better TD for its tier, able to compete in any game it is placed in.


Early Research

  • The Continental R-975-C1 engine and the 57 mm Gun M1 L/50 carry over from the T82 and can be installed immediately.
  • Research the upgraded suspension first.
  • Next research the SCR 610 radio.
  • Go from there.

Historical Info

The 75 mm Howitzer Motor Carriage M8, sometimes known as the M8 Scott, was a self-propelled howitzer vehicle of the United States developed during the Second World War.

Development

It was developed on the chassis of the then-new Light Tank M5 (Stuart VI). The test vehicle had the standard M5 turret removed, and replaced with an open-topped turret, this vehicle was designated the T17E1 HMC. Armament consisted of a new open-topped turret armed with a 75 mm M2 howitzer, later an 75 mm M3 howitzer, which were reworks of the M1A1 pack howitzer. It carried 46 rounds of 75 mm ammunition; types of ammunition carried were Smoke M89 and H.E. (High Explosive) M48. It featured no coaxial or hull mounted Browning M1919A4 .30-06 machine guns as featured on standard Light Tank M5s. The only other armament was Browning M2HB .50-caliber machine gun for local area, and anti-aircraft defense; 400 rounds of .50-caliber were stowed onboard for the M2HB.

Production

The T17E1 HMC was ordered into production as the 75 mm Howitzer Motor Carriage M8 in April 1942. Production ran from September 1942, to January 1944. A total of 1,778 vehicles were produced.

Combat Service

The M8 saw action in the Italian Campaign, the Western Front, and in the Pacific Theater of Operations during the war. It was used by the French Union and State of Vietnam during the First Indochina War. It was largely replaced by the adaption of the M4 Sherman to use the 105 mm howitzer.

Variants

  • 75 mm Howitzer Motor Carriage M8

Based on the Light Tank M5 chassis.

  • 75 mm Howitzer Motor Carriage M8A1
Based on the Light Tank M5A1 chassis. Some rearmed with the M3 75 mm gun.

Historical Accuracy Errata

The following are consensus errors or inconsistencies which have been identified with the configuration of the vehicle in question and conflict with information available on the public record. The causes for these divergences in the game are normally not disclosed and may be rooted in game balance.

Actually a self-propelled gun, not a tank destroyer.
  • Actual gun elevation is -20°/+40°. In World of Tanks, however, it is only -10°/+25° (-8°/+20° when upgraded).
  • One of its historical armaments, the 75 mm M2 howitzer, is missing.
  • Neither the 57 mm Gun M1 nor 3-inch AT Gun M7 were developed for the M8A1.
