O' Brien was head of the research department at Stark Industries and a close friend of Tony Stark. O' Brien also knew that Stark was Iron Man. Stark had O' Brien build the Guardsman armor in case of an emergency.
A time came when O' Brien put on the Guardsman armor to help Iron Man in battle but a malfunction in the cybernetic circuitry stimulated jealousy and rage in the brain.

Michael O' Brien
Michael O' Brien first appeared as himself in Iron Man vol 1 #82 and then first appeared as the Guardsman in Iron Man vol 1 #97.
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.
