3. COMMANDERS ARE DIRECTED TO ALLOW ELIGIBLE AND INTERESTED VOLUNTEERS WITHIN THEIR COMMAND TO ATTEND SCREENING AND PARTICIPATE, IF QUALIFIED, IN THE FINAL ASSESSMENT AND SELECTION (A&S) IN A TAD STATUS TO MARSOC. RSAS WILL IDENTIFY INDIVIDUALS WITH THE ATTRIBUTES THAT ARE REQUIRED BY MARSOC SO THAT SELECTED MARINES CAN UNDERGO THE REQUISITE TRAINING IN COMPLEX SPECIAL OPERATIONS SKILLS, SKILLS UNIQUE TO SPECIAL OPERATIONS CONDITIONS AND STANDARDS, IOT OPERATE INDEPENDENTLY OR IN SMALL GROUPS.

4. MARSOC WILL FOCUS ON RECRUITING, SCREENING, ASSESSING, AND SELECTING MARINES THAT WILL SERVE IN OPERATIONAL BILLETS WITHIN THE FOREIGN MILITARY TRAINING UNIT (FMTU) TEAMS AND THE MARINE SPECIAL OPERATIONS BATTALIONS.
PMOS BILLETS THAT ARE THE FOCUS OF RSAS EFFORTS:
8007 (UNRESTRICTED GROUND OFFICER) LT — MAJ
0302 (INFANTRY OFFICER) LT — MAJ
0311 (RIFLEMAN) LCPL-SGT

5. MARSOC WILL RECRUIT THESE MARINES THROUGH THE NORMAL ASSIGNMENT PROCESS, IN CLOSE COORDINATION WITH MMEA/MMOA, AND THROUGH VOLUNTEERS/RSAS SCREENING. THE TARGET POPULATION WILL BE MARINES WHO ARE NEARING THE END OF THEIR FIRST TERM OR WHO ARE NEARING THE END OF THEIR STANDARD 36 MONTH TOUR OBLIGATION (TWO DEPLOYMENTS, PREFERRED, WITH THEIR PRESENT UNIT AND/OR THREE YEARS ON STATION AND ELIGIBLE FOR PCS/PCA ORDERS). TIME ON STATION WAIVERS WILL BE CONSIDERED AND APPROVED ONLY BY MMEA/MMOA.

6. PRIOR TO THE CONDUCT OF RSAS VISITS, THE MARSOC G-1 WILL COORDINATE WITH THE APPROPRIATE MARFOR G-1 (MARFORPAC/MARFORCOM) AND CG TECOM G-1 TO SYNCHRONIZE AND MAXIMIZE EACH RSAS VISIT. MARSOC IS DIRECTED TO KEEP HQMC, M&RA APPRISED OF ALL RSAS VISITS AND SCREENING EFFORTS.
