Hero or Weapon?

Colonel Benjamin Tennyson wasn't you're average Colonel. He had repelled the raiding party on Mindoir as a teen, saved Elysium, and tore through Torfan. He climbed the ranks of the Marines, all alongside his best friend Commander Rachael Shepard. Now he is to face the might of the Reaper army before the Cycle commences. Good thing he has a watch to tell him what time it is.
