What do you want to do? If you don't say where you want to go, it will be defined for you by your reader - security/gov contracting. It would be helpful if you could do some thinking as to how an additional higher level degree will expand your mindset and change your career trajectory vs. what it would have been otherwise. You've got some extremely in demand skills (and articulate your experience well), veteran hiring preference, GI bill, and clearance, so you should be looking good at any of your desired programs. Hard to give any additional input without knowing where you want to go with your degree. If you want to double (triple?) down on your security focus you might take a look at Georgetown's MA in Security Studies. That's a quite a nice degree for certain veteran types who want to transition into in-house corporate security at household name corporations. SAIS would probably be the other best option for you as some of their grads seem to land some of the more lucrative gov consulting/contracting positions.
Hey Sorry about the delayed response. My goal is to working as a political officer with security focuses for the State Department and station in Beijing China. my research is to focus on how our "Asian-pacific Pivoted' defense policy influences the South China Sea disputes, and what are some of the possible solutions to reduce the current tensions. Yes, you are corrected, the field I applied is very security policy focused, especially with Fletcher and SIPA. I actually didn't make to SAIS early notification round, my application is being deferred to the regular round. I applied the following schools; American, Tufts, SAIS, SIPA, Elliott, Harvard, and Berkeley. My dream schools are actually Tufts, SIPA, and SAIS. Nevertheless, I will be delighted to go any of those programs. Thank you for reply have a wonderful new year.
