This is for retired military personnel who have a combat-related Department of Veterans Affairs (VA) disability rating between 10% and 50% effective January 1, 2004. CRSC may entitle you to additional funds which are designed to compensate you for the reduction of your military retired pay due to the receipt of Department of Veterans Affairs (VA) compensation (also known as the VA waiver's). With CRSC, you can receive either partial or full concurrent receipt of your military retirement pay and your VA disability compensation.
