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.

T56 GMC


III

AnnoA109_T56_GMC.png

30000

The T56 GMC is an American tier 3 tank destroyer.

Development of a 3 inch self-propelled gun on the M3A3 Stuart chassis started in September 1942. Trials on the Aberdeen Proving Ground in November demonstrated that the gun was too heavy for the light tank chassis. Never entered mass production.

The T56 GMC recently replaced the T82 HMC, which is now a tier four arty, as the tier three TD. It has decent mobility and a good choice of guns. As such it plays as a mobile sniper, moving after only a few shots. But with pros always come cons, and the T56 is no exception. The T56's view range is far from outstanding (It is tied for the worst), and the armor, while it looks decent on paper, is non-existent. Even so the T56 GMC can be very fun and enjoyable to play, and can easily compete in tier five matches.

The T56 GMC marks the end of its American tank destroyer line.

Player Opinion

Pros and Cons

Pros:


  • Good mobility
  • Very good DPM with 57mm
  • Nice alpha damage with 76.2mm
  • Very good penetration for a tier 3, even with the stock gun


Cons:


  • View range is awful, blind as a bat
  • Only the hull has decent armor, the gun shield is paper thin
  • Somewhat sluggish to reach its top speed
  • HE shells result in a quick death for this tank


Performance

This Tank Destroyer is best played as a sniper or second line fire support. Both guns have excellent penetration, and aim time is only 2.2 seconds. When spotted, move your position.

Historical Info

The T56 3in Gun Motor Carriage was the first attempt to fit a 3in gun on the chassis of the M3 light tank. The T56 was based on the final production version of the M3, the M3A3, which had a greatly enlarged superstructure that almost reached the front of the tank. On the T56 the turret was removed and the engine moved forward to the centre of vehicle. The heavy 3in gun was mounted at the back of the vehicle. The rear panel of the superstructure hinged down and back to form a platform for the gun crews. A limited amount of protection was provided by a boxy shield that covered the gun mounting, and provided limited top and side protection. Work on the T56 began in September 1942, and a prototype was built quickly. The M3 wasn't really suited to this sort of conversion and the weight of the gun meant that performance was poor. An attempt was made to improve the design with the designation T57 3in Gun Motor Carriage, but this was also unsuccessful and both programmes were cancelled in February 1943

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.

* The T56 was only ever fitted with the 3 inch gun.
