U.S. Marine Corps Staff Sgt. Michael Paugh, a platoon sergeant with Alpha Company, Battalion Landing Team 1/4, 15th Marine Expeditionary Unit, reaches the top of a cliff during assault climber training at Marine Corps Base Camp Pendleton, California, July 8, 2020. Assault climbers enable a unit to operate in environments that require the ability to climb and rappel, allowing Marine Corps units to move freely through terrain that would otherwise be impassable.
