o.k. lets get this squared away by the steps. first off, you said you were placed on tdrl on Jan 29. i'm assuming that was in 2008, if so, are you already getting paid?? if not, then you called DFAS recently, and theres no record of your pay being entered,at 30% you will get 50% while on the TDRL. BUT!! you have to apply for CRSC through the USMC in order for your pay to be tax free, as it is combat related. YOU yourself has to do this, your service wont apply for you. they will however give you CRDP automatically, which is taxable, but you cant have both. heres the fix...download a DD 2860 (application for CRSC) attach all your documents which are listed on the application,retirement orders,3349, DA 199,purple heart orders, everything,, and send it to the USMC (address is listed on the form) they in turn will forward therequest to DFAS (when the USMC approves your application)and if it its shown your injuries have a casual relationship to combat, your money will be tax free. also to collect concurrent pay from the V.A. and the Marine Corps, you still have to apply for CRSC , which is outlined in the 2008 national defence authorization act. this is for all service members. the high 3 you spoke of is "by law" if you entered the military prior to aug 1980, your pay is calculated by the highest rank held satisfactorily. if you joined the service after august 1980, your pay is calculated by your last 3 years average pay. hope this helps. i feel confident in stating this that if you were retired Jan 2008, and apply for CRSC, everything should be fine. dont put it off. it may take up to 60 days for the Marines and DFAS to get everything plugged in. I'm in the same boat except i first joind the USMC in 1979, and therefore paid as an E8, my highest rank held. good luck.my retirement date becomes effective 27 Feb,09. i called DFAS last week and was told the same thing, apply for CRSC, which i had sent it off already as soon as i got my orders in my hands. i have yet to get paid yet, but the military side should be looking at my application pretty soon. the military (as i was told by DFAS last week) pays one month behind, so if you retired Jan 2008, i wouldnt expect anything until atleast march 09....good luck....
