Benefit Fact Sheet
Concurrent Retirement and Disability Pay (CRDP) allows military retirees to receive both military retired pay and Veterans Affairs (VA) compensation. This was prohibited until the CRDP program began on January 1, 2004. CRDP is a "phase in" of benefits that gradually restores a retiree's VA disability offset. This means that an eligible retiree's retired pay gradually increased each year until the phase in was complete effective January 2014. You do not need to apply for CRDP. If qualified, you will be enrolled automatically.
Army National Guard Soldiers on state active duty are not eligible for CRDP. CRDP is only applicable to retirees who have completed at least 20 
years of service. Soldiers who retire with less than 20 years of service such as disability retirements are not eligible for CRDP.
