USMC Helicopters' ammo in Vietnam

[void1984]

Is it pure gaming decision to weaken the helicopters, or were they carrying really so few ammo?

Air mounted MGs & cannon tend to have a much higher rate of fire than ground counterparts as used to straffe, often have low ammo loads to so it does not last long.
In the case of the Huey think early ones just had a M60 MG mounted on each landing skid. Infantry can reload it not so easy in a helicopter.
