The Marine Corps has updated its activation deferment policy for Marines moving from active duty to the SMCR. Effective immediately, those Marines can defer involuntary activations under 12304b authority for up to 12 months from their AC EAS, no matter where they were stationed or what their current dwell status is.

Bottom line: If you just left active duty and joined the SMCR, you can defer involuntary activation for up to 12 months from your EAS, as long as you stay in good standing.

Who it affects

Marines who transitioned, or are transitioning, from active duty (comp code 11) to the SMCR (comp code KA). The 12-month window starts from your AC EAS, so if you already made the transition, the clock started on that date.

IMA and IRR Marines are not eligible for this deferment.

What you need to do

If you're an eligible Marine:

  1. Upon affiliating with your SMCR unit, notify your unit admin section that you want to elect involuntary activation deferment.
  2. Make sure you stay in good standing per MCO 1001R.1L (the MCRAMM). Falling out of compliance ends your deferment.
  3. You can volunteer for activation or waive your deferment at any point during the 12-month window if you choose.

If you're unit admin (S-1/admin section):

When an eligible Marine elects deferment, enter Unit Diary Type Transaction Code (TTC) 099-001, the appropriate mobilization status code, and set the Mobilization Elective Deferment Algorithm (MOBEDA) date to 12 months from the Marine's AC EAS.

Key dates

  • Effective: Immediately
  • Deferment window: 12 months from each Marine's individual AC EAS date
