U.S. Army Spc. Lain Fresnova, 689th Rapid Port Opening Element, 832nd Transportation Battalion, 597th Transportation Brigade signal support systems specialist, hammers a metal post into the ground, to hold a raised pole for a better communication signal during Exercise Turbo Distribution 18-02 at Fort McCoy, Wisconsin, Sept. 9, 2018. The elevated post would allow the signal to reach from the forward cargo yard to the flight line, so the two separated locations could communicate.
