OSUT 

One Station Unit Training. It's a military term meaning that your Basic Combat Training and Advanced Individual Training are at the same place, instead of moving from one fort to another.

When Nina trained to be an MP, she did all her training at Ft. Leonard Wood in OSUT format instead of moving after BCT.
