Most RTP programs are going to require you to either come out of pocket or use some portion of your GI Bill. Start getting your ratings now knowing that you are basically just "paying up front" your portion of training. This will also allow you to be more flexible when choosing which RTP to use. Who knows, you may find enough grants, ed. benefits, etc. to not even need an RTP. This will allow you meet R-ATP requirements and be able to apply anywhere.
