Yeah, just because there is a long gun on a bipod in front of them, a spotter scope to the right, and a range card conveniently taped to the knee wall doesn’t NECESSARILY mean they are a sniper team.
However, it might be “a clue”.
O/T and training? The ‘training’ part bothers me.
Yeah, a guy who comes out on stage with cymbals attached to his knees, a harmonica on a frame in front of his face, a banjo, a guitar, a tambourine and a drum with a foot petal is not necessarily doing a one man band routine, he might be about to recite some Shakespeare.
