Admitedly helos can be reloaded rather frequently, why supply post is right on the front not traveling vey far. Pretty sure this did happen in real life without checking in Vietnam for instance when strategy changed & attacked citys helos were based at one popped up shot & back at reload point in 5 minutes. Or how about Black Hawk Down situation in Somalia think base was pretty close then not sure.
Simple agreement between players can sort ammo reloads while not entirely realistic Dumps bunkers only allowed if defending makes reload times long if have missiles. More complex & can of course cheat play with people & only thing we change names of is ammo supply vehicles. Arty Sam ATGM Arms - only use to supply right type of unit keeping simple ATGM includes helos Arms is tanks AFVs. Never used but could also agree say only one reload allowed.
