Grif and Simmons flee from Caboose and Sheila; Grif abandoning Simmons after he had hatched a plan for a joint escape. Once Caboose manages to activate the auto-fire mechanism, the tank begins to systematically target and destroy everything present. Sheila subsequently hits the Warthog, sending it flying, but Grif and Simmons continue to flee and successfully evade the cannon fire. Church becomes the next target, however, and is killed when Caboose fails to deactivate Shiela's auto-fire operation; Tucker accuses Caboose of team-killing ("You shot Church, you team-killing f***tard!").
