How about you look at choppers in BF2? They could be hurt with small arms, but only M95 and PKM could damage them reasonably. Multiple car machineguns could make short work, but the helo has a TV missile that outranges them. A tank shell would make a helicopter start heavily smoking.

AA systems are the way to go anyway, they can take out helis with their cannons and SAMs.
