There are two pages on Facebook, that I am currently aware of, that specifically focus on Buddhists serving in our U.S. Armed Forces:
"Buddhists in the Armed Forces" (an open group)
"U.S. Military Buddhists" (a Facebook page)
These are great ways to connect with your fellow Buddhist servicemember, learn about Dharma groups or temples in your location, and having your questions answered about Buddhism and military life. There are many more of us out there than you may assume!
