I am about to be commissioned in two weeks. Have 7 years in service so far. Does my time as far as high year tenure goes start fresh once I commission? Phrased another way, can I potentially stay in 37 years if I haven't been passed for promotion (not that this is what would happen or what I would do) or would my 7 years count against me when it comes time for me to be forced out? In essence, if I'm at or past the twenty year mark and have not made a certain rank could they potentially make me retire due to my enlisted service? I know this sounds kinda complicated but maybe one of you guys knows what I'm talking about.
