The AT gun can be upgraded to a Helicopter Gunship, I know this because I have done it in game Sneak+stab 17:29, March 14, 2012 (UTC) Sneak+Stab
- Thank you Sneak+stab. I checked the AT gun and and the AA gun, both of them didn't list the correct upgrade information. Fixed now. Next time just edit it though. Jake Von 08:49, April 15, 2012 (UTC)
