(Tonya Smith/Marine Corps) The Marine Corps may soon have new green-on-green physical training uniforms. The Corps announced it will start a trial run of a more modern uniform, with a slightly different look. The new shirt will be more form fitting, feature “USMC” insignia in reflective silver on the back, an Eagle, Globe and Anchor on the sleeves, and come with a mesh side panel for breathability, a Marine Corps press release said.
