"Banner didn't have a clue what he was doing. That said, neither did any of us, but he was our leader. He was supposed to lead us."

— Ashley M. Williams, describing her former CO.

Staff Sergeant Stephen Banner was a marine in the Systems Alliance Marine Corps who was the commanding officer of Dog Squad, a detachment of the 212th Planetary Defense Group stationed on Eden Prime by 2183 CE. Stephen Banner was born on Earth, having served in the Royal Australian Marines for a short period before transferring to the Systems Alliance Marine Corps, going through a brief period of transitional training before being admitted. He was assigned command of Dog Squad in 2182 CE, although it wasn't considered an honor due to the 212th's general reputation as being "hell for the unaccomplished". Banner's inexperience in the field of command became too apparent when the geth attacked Eden Prime in 2183 CE, with Banner being killed during the initial stages of a geth ambush.
