U.S. Marines set up and test equipment during a high frequency (HF) training event between Camp Pendleton, California, and Camp Schwab, Okinawa, Japan, Jan. 14, 2020. <br /><br />This training between 1st Marine Division and 3rd Marine Division allowed both units to train in HF communications over the Pacific Ocean. The training helps the units maintain a low electromagnetic signature which allows for distributed operations without detection in the operating environment. <br /><br /><br />-----------------------<br /><br />Credit to : U.S. Marine Corps video by Lance Cpl.
