Evacuate Camp Rogain
Camp Rogain has been cut off and is surrounded. Either call in CAS-EVAC and hold out till it arrives or go it on foot.
If you are looking for a Very difficult mission to accomplish, attempt to hold Camp Rogain until CASEVAC arrives. You can call in CAS and CASEVAC to your location to attempt EXFIL that way, or you can go a-foot. It is best to have a full 8 man team. There are 2 fire-teams to slot into.
