Pax lays flat on then ground in a line, Q says go. Everyone hops up similar to recovering from a burpee, and sprints 5 - 10 steps, then dives down flat on the ground remaining in line. Essentially, you're advancing the field without the enemy fire being able to smoke you. Go hard, go quick. After getting to your resting place, complete upper, and core routines, then do a different upper, core routine, then belch back to the starting point, mission accomplished.<br /> Best on grassy fields in the gloom with some morning dew, some dives have slides, one must reverse low crawl to get back to the line or forward low crawl to advance to the line.
