Hello everyone, an explanation of the "Char B1" tank
Many readers do not understand why the article uses the "Char B1" tank with two guns.
This was actually determined by the fact that there were no dedicated tank guns in World War I.
There are usually two requirements for tanks: one is to fight against tanks, and the other is to coordinate infantry attacks.
The former requires the tank gun to be flexible and have a large firing angle, and the rotating turret can perfectly meet this requirement.
The latter requires caliber.
Small-caliber artillery cannot cause much damage to enemy fortifications or bunkers, and large-caliber artillery is obviously more lethal.
However, during World War I, it was impossible to install large-caliber artillery in the turret, otherwise it would be impossible to aim or even load ammunition because the breech block was too long.
Only by shortening the breech block and developing a dedicated tank gun can the two be unified.
Before this, the only layout that could meet both needs of tanks was the "Char B1".
Even during World War II, there were still tanks with this layout, such as the American M3 medium tank (Seven Brothers Coffin). The reason was that the breech block could not be shortened in time and there was no suitable tank gun, so it could only use this layout in battle.
Otherwise, it is very likely that the tanks will encounter indestructible enemy fortifications on the battlefield, causing serious problems such as being unable to advance or retreat.
