Spencer Stone, the American Airman who alongside three other men stopped a gunman in a high-speed train between Holland and France last month had this to say about his experience.

“I 100 percent believe that Brazilian Jiu-Jitsu saved my life at that moment,” Stone told Air Force Times on Wednesday. “Every move I used on him was very, very basic — you can learn in five minutes. If we had a course like that in the Air Force for people to learn basic moves, it could help anyone in a situation like that.”

Stone, who was injured during the struggle with the alleged terrorist, is a white belt and trains at the base he is stationed at the Azores archipelago, in Portugal.

The US Air Force service man who jumped on top of a terrorist carrying an AK-47 riffle inside a high-speed train between Amsterdam and Paris this Friday is a Jiu-Jitsu white belt.

Spencer Stone apparently trains at Gracie Lisboa’s branch at the Terceira Island in the archipelago of the Azores, in Portugal.

According to the academy’s Facebook page, Stone trains with instructor Simão Reis.

Stone and two other American military tackled the 26-year-old Moroccan national to the ground after hearing him load up a gun in the toilet.

Stone’s father told CNN that his son put the attacker in a choke hold.

Stone was injured in the back of the neck and almost had one of his thumbs severed by the terrorist, who pulled a knife.

He went under surgery in Paris and his condition is considered stable.
