If I'm really wanting to get a last huzzah in...paintballs.
Loaded with something stickier (I'm thinking tar or pitch) I might be able to hit a jeep's windshield, shoot the occupants with my pistol, stash the bodies in the back, and convince everyone we were all killed so nobody shoots at me for the rest of the fight. Also helpful for partially blinding battlearmor to aid in your escape.
