 At Exercise 4 Slight, U.S. Marines plan a route for their squads during a live-fire scenario for their Japanese counterparts. Marines start the event with the tactical calling formation to get to the range. They move through tall grass to avoid detection and route to their destination as the Japanese ground self-defense force observe their movements. It's pretty hot out here and it's pretty rough running with the gear and just gives us a new mentality on how hard it was for Marines in the past. Other troops are using the MK-153 rockets and M-240 Bravo to ensure targets are being taken out. It's extremely fun. You get to shoot as many rounds as you want, accuracy by volume, that's all it is. Watch the targets explode. Reporting from Hijidai Manoeuvre area, Japan, I'm Seaman Stefan Jackson.
