[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.

The T18 HMC is an American tier 3 self-propelled gun.

A proposed 75 mm howitzer on the chassis of the M3 light tank. Developed by the Firestone Tire and Rubber Company in the fall of 1941. Two prototypes were ordered after the project was approved. The first vehicle was produced in May and underwent trials in June 1942 on the Aberdeen Proving Ground. The project was discontinued in favor of more promising designs.

Formerly the tier 2 American TD, this SPG was replaced by the T3 GMC and moved over to the SPG line in 9.12

The T18 HMC leads to the T82 HMC.

Player Opinion

Pros and Cons

Pros:


  • Has 50 MM of frontal armor, which can bounce same tier shots
  • Very good reload
  • Due to it's great frontal armor and reload time, TD mode is definitely possible


Cons:


  • Armor will not stand up to tier 5's
  • Has almost no splash damage, hitting near an enemy will do minor damage
  • Gun cannot compete with Tier 5 heavies, even with HEAT loaded.


Performance

Originally part of the American tank destroyer line, the T18 quickly became a favourite, owing to the combination of excellent armour and a powerful gun that could one-shot kill any tank of the same tier or lower. As artillery it can still work well as long as it is top tier, having excellent mobility and relatively strong armour. It also has a good rate of fire and relatively good accuracy for its tier, which makes it relatively easy to play for inexperienced artillery players. Its main drawback is the very low alpha-damage, which renders it largely useless in Tier 5 games due to its inability to damage heavy tanks. In lower tier games this is not a problem thanks to the lack of heavily armoured vehicles.

Historical Info

The T18 Howitzer Motor Carriage was an American self-propelled gun. Its development started in September 1941 as a close-support vehicle using the M3 Stuart's chassis. A 75 mm howitzer was mounted on the right front of the vehicle. The gun mount was adapted from the M3 Grant. Two prototypes were produced by Firestone and then sent to the Aberdeen Proving Ground. However, they were unsatisfactory because of their high superstructure and nose weight. Because the Army disliked the high superstructure and nearly vertical armor, the T18 was abandoned in 1942, and soon started a new turreted project, the T41 75 mm HMC, also known as the Howitzer Motor Carriage M8.


Later, the prototypes were kept on display in the Aberdeen Proving Ground until they were destroyed in 1947.
