lmao.
RPGing choppers is a pain in the ass. lol. I always just miss the guy. I think I've shot 2 choppers down with RPGs out of the 30+ shots I've taken at them. I'll give you props for being able to take them down. Theres some decent videos on youtube for RPG takedowns too.
I had a joker / batman moment like that once. I was on a team getting base rapped on Kharg Island. Every time I spawned I jumped into one of the tanks that are on those deployment ships at the coast line.. These 2 jets kept doing runs on me and everyone else. After one jet flew by, I'd jump out and repair, jump back in, switch to machine gun and start firing at the next one, jump out and repair, etc. They killed me twice, then I got fed up with it and spawned with stingers.. they kept flying straight and the stingers could never catch them. So annoying.. so I jumped back in a tank and I lucked out near the end of the match. I lined up a couple shots with the main cannon, missed the first guy, but nailed the second one right in the cockpit. That explosion was awesome. The jet parts were flying right at me. The guy I shot down sent me a message.. he said "Nice shot". That was an epic moment for me. hahaha.
