Andrew had hung back and kept his head on a swivel. Patroling the outer range, he took photos of the structure from all outsides. He let the others do the exploration and did indeed take the offered break to snack on a power bar then wash it down with a swig of his canteen that had a packet of kool-aid in it for flavor and a sugar boost. It was something his family did back since nam. When it was time to be boots up, he took third position and switched from shotgun to grenade launcher in case they encountered anything heavy. As they came upon the tracks, he took a picture of them for the eggheads back at base, the boss was taking pictures of the signs. But now it was time for first contact. Firing an explosive into the group was a recipe for disaster, so he switched back to shotgun but kept a relaxed position. His weapon was armed with alternatig rounds of birdshot-buckshot-slug. He set his phone to record and put it in his chest pocket. Hoping for the best and planning for the worst.
