Continuity issue: In previous flashbacks, we've seen Rob's rank as Sergeant First Class -- indicated by the two "rockers" under the chevrons on his sleeve. But in this episode, he's either been busted two ranks -- to sergeant -- or there's just been one of those continuity slip-ups. He also appears to have changed units, as his divisional shoulder patch has changed. (He also displays the in-between rank, Staff Sergeant, in one episode).
Adamo sighting: A soldier in the PX who makes a pass at Millie.
