Heroes in literature and in movies. People you admire for what they are.
Conan, Sidney Carton, Scarlett O'Hara, Paul Baumer, Ender Wiggins, Paul Atreides and Stee Jans from literature.
Archimedes, Pythagoras, Hooke, Boyle, Pascal, Rutherford and van Bohr among others in the sciences.
George Washington, Thomas Jefferson, John Paul Jones (the USN was my branch), Stephen Decatur, Anthony McAuliffe and the men @ Bastogne with him, the French defenders @ Bir Hakeim, Anzacs @ Gallipoli were all bad motherfuckers.
One hero who's name I don't know is a Chief on the USS Forrestal who ran out on the deck to save a pilot who's canopy would not open due to damage from the fire. With the plane about to be enveloped in flames he raced out with a 15 lb fire bottle in each hand (they actually weigh 30 - 35 lbs gross) and just before he reached the plane it all blew up. The USN shows the Forrestal fire film to all fire fighting classes to illustrate the importance of doing your job and teamwork. I saw it in the 3 day intro class @ RTC in San Diego and in the 2 week class @ FRAMP School @ NAS Norfolk.
