Was the AC-47 gunship around for WWII? Would be sweet if it were... Hehe
Gunning down towns from orbiting AC-47's... Hopefully we'll be able to have more than one gunner per plane some day.
As for the formations, I say YES to C-47 formations, but keep the number of troops needed to take the city the same... The kicker: Don't allow C-47's to release troops from the ground! I think the land-then-roll-to-town-and-hop-out-of-the-C-47 thing is a bit... lame...
It'd be sweet to watch C-47 raids (like d-day) dropping hundreds of troops while ground and air forces try to eliminate them before they take the town. Would really make the captures a lot more exciting than they are currently (for both sides).
