What are your favorite partner or team exercises in boot camp?

We put our boot campers in groups: they form a circle interlocking elbows. We take one from the group and have them turn around, separate from the others, while we put a scarf or glove in the back pocket/pants of one of the boot campers in the group. The solo person then returns and has to pull the item out of the pants while the group runs in a circle in all directions trying to not allow this to happen. It creates tons of laughter and camaraderie.
Each boot camper has their turn to try.

We also use hills for drills. One person runs up the hill while their partner does a series of exercises below, then they switch.
