After the discussion, Shire and Colonel Estiny eventually decided to set the additional armor at a thickness of 20MM.
This provides a lot of benefits for the tank.
First, it is more flexible in terms of mobility. When there is no battle, the additional armor can be removed and transported by vehicle, and re-installed during battle.
This not only increases the tank's mobility but also reduces the engine's burden, thereby extending its operational time.
Secondly, with this 20MM additional armor, its frontal armor reaches a thickness of 45MM.
Originally, the German Army's anti-tank rifles could possibly penetrate the "Shire A1" at around 200 meters from the front, but now it is basically immune to them, even at 50 meters or closer.
Lastly, it would certainly have an advantage in tank battles.
20MM of additional armor may not seem like much, but having it or not often makes the difference between life and death on the battlefield.
