What is one requirement during the high crawl exercise?

Maintaining contact on the ground with elbows, knees, and torso during the high crawl exercise is essential for several reasons. This technique ensures that the body remains low to the ground, making it more difficult for an enemy to detect a Marine while in a prone position. Keeping these points of contact provides stability and balance, allowing for smoother and more controlled movements. Furthermore, this method effectively simulates the tactical, low-profile movement necessary in combat situations, enhancing the overall effectiveness of the exercise. Proper form and mechanics help to reduce the risk of injury and improve the ability to navigate challenging terrains while staying concealed. This focus on maintaining contact is foundational in developing the coordination and agility required in real-life scenarios.
