Also I think its difficult for guys fr/ other services to understand Marine Deployment cycles.

With or without the GWOT Marine units cycle thru work-up & deployment periods whether its the MEU(SOC), UDP, or UNITAS/WATC/LFCARAT. So there are always going to be a # of BNs tied up in the work-up cycle.

Also there aren't particular units designated SC units. Just like the MEU(SOC) all BNs will cycle thru a SC MAGTF deployment cycle and move on to a different cycle upon completion of that one.

Regimental HQs will be designated x-region to specialize in, but this will mostly come into play Pre-Deployment during the workup phase, and in facilitating whichever Inf. Comp-Dets are deployed in there regions fr/ the US almost like a Mini-Theater Command; however without tactical control.
