Sgt. Fauxhall is a Military sergeant.
Sgt. Fauxhall has Crypto do a couple of jobs for him, like capturing Clayton Cartwell Jr. (an AWOL hippie who wants to avoid the draft) and kill a rogue military soldier, Private Danza who is selling bazooka crates to the KGB.
All is well for Fauxhall, until a KGB agent recruits a disguised Crypto to kill him and retrieve the bazooka crates.
