U.S. Marines Sgt. Chase Schmidt (left) and Cpl. Jacob Worshan set up an antenna during a long distance, high-frequency communications training event held on Camp Schwab, Okinawa, Japan, Jan. 14, 2020. This training between 1st 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 that is virtually impervious to meaconing, jamming, and interference, which allows for distributed operations without detection in the operating environment. Schmidt, a native of Gulf Breeze, Fla., and Worshan, a native of Calhoun, Ga., are radio operators currently under 4th Marine Regiment, 3rd Marine Division. (U.S. Marine Corps photo by Lance Cpl.
