Correct if I'm wrong, but isn't it a little suicidal to stick your head out the top of a tank during a firefight?
If so, why not have a machine gun system similar to what Apache gunships have?
What I mean by that, is why not have 25mm Chaingun on the turret, with a lead in the mount that goes down through the armor to connect to the machine gunners helmet?
Thus the gunner can see what his gun sees and shoot things without having to stick his squishy head out?
Can anyone help me please? Thanks.
