[Hectic]

Sniper no machine gunner yes. A sniper even with an m14 would be prety useless from a chopper. Youd need at leas c mag or box mag itll be alot of rounds fired per target hit even a hi cap mag wouldnt quite cut it me thinks.
To the OP your idea is awesome would be cool to have the advantage of over head recon and add a new depth to the game securing control centre and the missile launch sites, heck houd hardly need any other side objectives just a main one to go along with those things as most folks would be crazy busy tryin to secure missile launch sites befor securing the command centre. Once you had all those under controll youd prety much have a cake walk to the final objective
