Split Op 

A program where soldiers split their Basic Training and Advanced Training in half - resulting in Advanced Training being typically completed the following year.

Split Op recruits are renown for hanging out with Recruiters and tend to be ate-up upon completion of their Advanced Training.

That Split Op soldier sure is a pussy.
