It works in the Corps the same way it does for everyone me old china:
Warned for deployment. PDT. Deployment. Recovery.
In the Corps you can go as an individual augmentee or as part of a formed Section. Plans can change at the last moment and you could end up somewhere you wern't expecting. Its all part of the fun.
Also, don't call them Warzones. Remember that military lawyers will tell you that war is a legal state. Just because we have expended more ammunition in Afghanistan than we did in the Korean war does not mean we are at war.
