Once in, Vratsanos -- a random, non-military dude off the street -- formed a sabotage squad called Olympus. They quickly secured a reputation as the go-to mad bombers against the Axis powers.
Despite Vratsanos himself not having a clue on how to make or rig bombs, in three short years Olympus blew up 36 bridges, 47 railroad depots, 32 trains and over 3,000 Axis soldiers.
And only some of them were on purpose.
But most impressive were his actions in February 1944. Working completely alone, Vratsanos scouted a German train, rigged it with explosives and blew it right the hell up, walking calmly away with his back to the inferno.
