Poppers. Possibly if an area existed where guards carried flame throwers, they could have become infected. They wouldn't know to use the "Gun" they have, so they wouldn't attack with it, but if you shot one in the chest, they may blow up(higher chance of "popping" if you use a teir 2 gun), possibly on you, other survivors, or other infected.
