I want to give the tank a coincidence rangefinder......
In this mock-up attempt, the commander's machine gun is kept. I want to use the BESA machinegun, but its only auxiliary turret application I think think of is the early marks of Crusader tank, and I am not sure if I want to adopt the scheme on the Crusaders......
What is the useful elevation of a machinegun cupola? I mean, it's probably not going to be terribly responsive for anti-aircraft defense even against prop-driven aircraft, but is shooting at enemies in elevated positions (like higher floors during urban operations) important enough of a consideration when adding tertiary armaments to tanks?
Or...... ought I just get rid of the MG and lower the rangefinder to within the height constraint of the original commander's mini-turret?
Thanks in advance. Comments and suggestions welcomed.
