Yeah, but...<br/>I-...<br/>Wait...what?<br/><br/>Okay, wait.<br/>He was a Petty Officer Second Class (the Navy equivalent of an Army Sergeant) in the S-IV program.<br/>The acronym for Petty Officer Second Class is PO2.<br/><br/>In the story he was transferred to the UNSC Army, and then demoted to Private First Class (PFC), which Is the 2nd lowest rank in the Army (and the lowest rank in the Marine Corps but that's irrelevant).<br/><br/>So...there is no way, right now, he would have PO2 "insignias" on his uniform.<br/>If anything it would be the one stripe and rocker of a PFC.<br/>(And I should have mentioned it, I shall edit in a moment) He's wearing the Army Battle Dress Uniform (which looks like the Military Police Armor on Halo Reach)
