 Knew a Marine lieutenant who had commanded a platoon of Ontoses.  He was not impressed with their reliability.
If I recall correctly, Frank Rizzo wanted the City of Philadelphia to buy two of these, back when he was police commissioner.  For crowd control.
Wilson Goode did him one better a few years later.  Who needs an armored unit if you already have a city air force?
