What does this do
Japan Ground Self-Defense Force Sergeant Seijiro Kaharu, a 1st Training Unit battle management system operator from Camp Higashi-Chitose, Hokkaido, Japan, taps a second stage regulator during a JGSDF shadow program at Misawa Air Base, Japan, March 5, 2018. During their time on Misawa AB, JGSDF Soldiers learned how U.S. and Japan service members work together to accomplish tasks and introduced new ideas to enhance execution tactics. Misawa Air Base hosts the exchanges with JGSDF personnel twice a year, allowing their basic English course students to immerse in an English-speaking military environment, further improving the relationship between the two forces.
