A self-described "gun nerd," he posts photographs of himself posing with a confiscated rocket-propelled grenade launcher, and he named his blog after his M2 heavy machine gun. Between glory shots with guns and photos of the Jungle Falls Suite in Idaho, where he stayed with his wife while on leave, Ma Deuce Gunner (who never reveals his name) gives detailed descriptions of the new Iraqi army he patrols with around Kirkuk.
