Red vs. Blue

Check Out the Treads on that Chick (1x7)

:

While Church and Tucker lament their current situation, Caboose hops into the tank. The tank's artificial intelligence (AI) introduces itself as Sheila, and runs him through the tutorial mode. In an attempt to sneak up on the Blues, Grif and Simmons leave the Warthog and unsuccessfully try to go around the rock. Seeing that the Reds have abandoned their vehicle, Church and Tucker decide to grab it. The tank drives up behind the Reds and takes aim at Grif. This episode is followed by a "next time on Red Vs Blue" feature, which states "someone will die." and Sarge replies "I sure hope it's Grif."
