Crawling in combat situations is a useful skill. Crawling may be in the high or low stance.
The Soldier moves on his hands and knees, moving one hand and the opposite knee and then continuing to move the hands in alternation with the knees.
The Soldier is in the prone position. Pulling with both arms and pushing with one leg, accomplish forward movement. The other leg is dragged behind. The legs are alternated frequently to avoid fatigue.
