I recently read the story of Master Sergeant Roy P. Benavidez who in 1968 did what most people would not be able to do. In a volunteer mission to rescue fellow soldiers, he repeated exposed himself to enemy fire and hand to hand combat suffering 37 separate bayonet, bullet, and shrapnel wounds over a 6 hour battle and saved the lives of 8 men. Thought dead, he was finally pulled onto a helicopter and was in a body bag, being zipped up when he had just enough energy to spit in the face of the medic. When receiving the Medal of Valor, President Reagan commented that they should make a movie about his experiences, but doubted that anyone would actually believe it really happened.
What are some other real life tough beyond all odds stories that you are aware of?
