    Brief History

    O' Brien, New York City police sargeant, didn't believe that his brother, Kevin, died accidentally in battle with Iron Man. He re-opened the case without authorization believing that there was a cover up of Iron Man's actions. O' Brien managed to get access to the Guardsman armor and put it on hoping to go after Iron Man. O' Brien was affected by the faulty cybernetic circuitry and as the Guardsman, insane with rage, attempted to kill Iron Man. During the battle, Guardsman was convinced by Iron Man that the armor had a malfunction that caused irrational behavior. Iron Man removed the Guardsman armor from O' Brien and took O' Brien into his custody rather than turn him over to the police.

    After two separate battles with Sunfire and the Mandarin, Iron Man revealed that he was Stark to O' Brien. Stark repaired the malfunction in the Guardsman's cybernetic circuirty and the Guardsman hoped to make up for past mistakes. The Guardsman continued to be a reliable ally to Iron Man.

    Later, the Guardsman was the security director at Project: Pegasus but resigned a few years later and came to work for the Avengers as part of the support staff. Years later, O' Brien was contacted by War Machine who was recruiting close friends of Iron Man to fight Ultimo.

    The Guardsman was later stationed at the Super Villain Peniteniary known as the Vault.
