Army MOS composed of secretaries and wet backs.

Glorified secretaries that think they are a combat MOS. These pussies are the bitches of the Field Artillery and are known for their abuse of the "Don't ask don't tell policy."

The girls that have the 13 Delta MOS love having anal sex with each other.
