To give you folks an idea what that is like, OutServe will be publishing a column from Keith Thompson, a transman who is currently deployed in Afghanistan.
The command climate in my unit during pre-deployment was harsh for me. The Soldiers in my unit think that I am a lesbian, serving openly and proudly. They do not know I am trans. I have never had an issue with any of my immediate colleagues about my sexual orientation. Just before we deployed, however, we received a new “butter bar” in our ranks. I started to feel that I was treated differently from the rest of the crew, chosen for the jobs nobody really wanted. Most of all, I could tell that this officer had a huge issue with me. Whenever I attempted conversation with her, she would ignore me.
Here's the rest of Keith's column.
