Back in August 2015, an IS-IS terrorist boarded train #9364 out of Brussels. Equipped with an ammo to kill over 500 people, the terrorist may possibly have succeeded aside from three friends who refused to give into fear. One was a scholar, one was a martial arts enthusiast and airman first class in the U.S. Air Force, and the other was a member of the Oregon National Guard, also all three pals proved fearless since they charged and ultimately overpowered the gunman after he arose out of a bathroom armed and ready to kill.
