SF seeks one thing and ONLY one thing: the ability to be trained. Focus on what you have already been trained in and you'll be thought of as a deficit requiring REtraining instead of training.
Everyone in any SOG MOS begins as an equal. If you are trying to set yourself apart, you're not submitting yourself as an equal. Never sell yourself short, but never sell yourself apart.
If you ever get to any SF training, you will be nothing but a peer amongst many of your constituents. You'll also be surrounded by many other plebes with combat experience. You'll be required to show leadership and to submit yourself to others at the same time.
If you honestly believe that you can impress people enough to have a shot, you have no clue what any SOG unit works around.
