More damage from talons and the AA gun. Engaged a little bird (scout chopper) and it services 6 Missler from AA, yes they hit the target and were spaced out through reload time, the 20 MM gun was not doing enough damage between reloads. With in the engagement 2 teammates fired talons as well. Not to mention the 20mm canon is terrible against personnel, should not have to reload a 20mm when hitting someone literally there would be nothing left of the target after a few rounds
