If you reenlisted for the OPFOR bonus, you are not eligible to attend assessment and selection for MARSOC. You must meet the requirements of your contract.
An 0372 would have to request a lateral move back out of the MOS to return to the general purpose force upon completion of a 60 month tour.
0372 Operators receive at a minimum SDA level 5 which is $375 on top of base pay. Special skill sets gained while at MARSOC will add corresponding special duty allowances.
Currently 0372s do not fill SDA billets outside the command.
At this time MARSOC is not offering Assessment & Selection (A&S) slots to reservists.
