Ok this is it, since coast gaurd is federal agency as dhs primarily, equal opportunity employment commission rulings apply to them as a federal agency. My friend who told me this i know from being in the army. Shes DoD and i wont say more but her words are legit. I just asked her for some solid intel, and was told this:
"I dunno if there is going to be much info though, they're keeping the person's identity a secret for privacy reasons ".
Valid enough. As for other military branches, they most likely hold stringent to dadt rulings and policy for discrimination. SRS is most likely a requirement however as well as stealth for USCG service as relations with other branches are active. In the Army we did joint training with USCG stations in our area, so its most likely staying under wraps. Friends can only deliver so much intel. I know it to be 100% fact, but take what I say as here-say. Dont try applying for USCG unless post op.
