Fallout Equestria: Of Their Own Accord

It was a normal day when the 4th Marine Expeditionary Force and the 4th Russian Air Force Squadron begins a joint exercise. "Sherman, nice shooting!" Exclaims Major Dimitri Mosin Tubakov, leader of the 4th Russian Air Force Squadron, as Sherman pulls out a thumb up. Two US admirals, Admiral Grant Gerard DuGalle Calliope and Vice Admiral Vassily Aleksander Petrenko, watches the joint training exercise as birds are heard chirping.

However, a radio says, "An unidentified UFO just crashed near the joint training area where the United States Marine Corps Fourth Marine Expeditionary Force and the Fourth Russian Federation Air Force Squadron were located."
