U.S. Coast Guard Petty Officers 1st Class David Lee (top) and Royal
Hoang demonstrate proper stacking technique to Port Security Units
311 and 312 members on Marine Corps Base Camp Pendleton,
California, July 17, 2026. By stacking closely together, members
mitigate the risk of friendly fire, as it inhibits the lower teammate from
standing up. (U.S. Coast Guard photo by Petty Officer 3rd Class Chris
