Well it at least fits the first half of the thread title:
Two U.S. servicemen who tackled the bare-chested gunman who opened fire on a Thalys train from Amsterdam to Paris on Friday evening were lauded for preventing a potential bloodbath on the train. A third American, a Frenchman and a Briton also were reported to have helped in subduing the gunman.
The U.S. European Command, which oversees all American military operations on the continent, identified the Americans as U.S. Air Force Airman 1st Class Spencer Stone, on leave from Lajes Air Base in Portugal; Spec. Aleksander Skarlatos, a member of the Oregon National Guard; and Anthony Sadler, a civilian friend.
The two servicemen leaped into action after a French passenger confronted the attacker as he came out of a bathroom in Coach 12 at the back of the train shortly after it had crossed the border from Belgium into France. The attacker was armed with a Kalashnikov rifle, an automatic pistol and a box cutter.
Sadler told the Associated Press that they saw a train employee sprint down the aisle followed by a gunman with the rifle.
“As he was cocking it to shoot it, Alek just yells, 'Spencer, go!' And Spencer runs down the aisle,” Sadler said. “Spencer makes first contact, he tackles the guy, Alek wrestles the gun away from him and the gunman pulls out a box cutter and slices Spencer a few times. And the three of us beat him until he was unconscious.”
