Eighteen months after repeal of “Don't Ask, Don't Tell,” the policy which prevented gay and bisexual troops from serving openly, transgender soldiers must continue to remain closeted.

Repeal of the policy in late 2011 did not address transgender individuals. The military deems troops diagnosed with “gender identity disorder” medically unfit for service.

An anonymous 26-year-old specialist who is legally married to a woman and asked to be called Keith told the Military Times that he started taking male hormones during his deployment to Afghanistan and plans on completing his transition when he returns home.

“It's something I had always thought about,” Keith said. “My wife and I talked about it … and I knew I had her support, so I said, 'I'm going to do this.'”

Service members are required to report to their commands a significant change in their medical condition.

David McKean, a lawyer with OutServe-SLDN, which advocates on behalf of LGBT troops, called the policy unfair, saying fitness to serve “shouldn't be based on gender identification” but on “whether or not someone can do the job.”

Keith said he hopes he can remain in the military.
