Complete Warrior Achievement
Get a kill with the following weapons in a single life: Assault Rifle, Jet, Tank
You must get a kill with a Jet, a Tank, and with an Assault Rifle in one life! The preferred order to do this, and I think most will agree, is to get in a Jet at the start of the match and get a quick kill. Then either parachute out, or land and either hop in a Tank for a kill or shoot someone while getting the tank. The only saving grace is that this can be done on any map that has jets, like Caspian Border, Operation Firestorm, Wake Island etc.
