To comrade Mikoyan,
on the question of 1943 delivery of American tanks I report:
1. In 1942, we recieved two types of tanks from America: M3 Light and M3 Medium. Apart from that, 26 tanks M4A2 (medium type tanks) made it to the USSR with convoy 19.
2. In combat, a number of major issues appear on tanks M3 Light and M3 Medium, reducing significantly their combat quality.
3. The main issues are the following:
a) the tanks start burning easily when penetrated by shells
b) large dimensions with significant number of vertical armor plates make these tanks easily damaged from enemy anti-tank artillery fire of even very small calibers
c) little durability of the aircraft-type engines, installed into tanks
d) it’s impossible to shoot the sponson-mounted 75mm howitzer of M3 Medium tank, when the tank is in hulldown position, as the howitzer is located on ground level. It is also impossible to shoot two frontal machineguns that way for the same reason.
