Eric, I have no idea where you came up with that information but you might want to use google and actually read more than 1 resource.
It was designed to replace the expensive M1A1 Thompson and it cost the military more than $20 each. The "ordinence personel" was "ordinance technicians" a.k.a. military weapons techs and it was not designed for use by either aircrews or ordinance personnel...much more to the story than that.
think they were called "
Ordnance technicians"
ordinance: Orderly arrangement; preparation; provision
Ordnance 1. Military materiel, such as weapons, ammunition, combat vehicles, and equipment.
2. The branch of an armed force that procures, maintains, and issues weapons, ammunition, and combat vehicles.
3. Cannon; artillery.
sorry not to be a donkey, but I spent at least 20 min looking at the word thinking something was wrong with it. anyway I hope i didn't misspelt it either.
