When I was in the service in the mid to late 60s, Division G2, a gay guy joined our section.
He was stereotypically gay looking, effeminate, a bit of a lispy speech. He also did an ace job on all the "office" and "pencil whipping" tasks that came our way. He did his best to carry his load out in the field, and anyone who gave him a hand did it willingly because he carried more of his load at base.
He was assigned a single bunk room, don't know who made that wise decision but he roomed along, and if you happened to make a trip to the can in the wee hours you might notice him using the shower when no one else was around.
I was called into the Col. office one day and he asked me if I thought the guy was gay. I told him I was sure he was as I had seen h im necking in his car with a guy from Admin Co.
The Col. asked me if he has ever made any advances towards me or anyone else that I might know of. Told him that he never has and goes out of his way to avoid any situation that might make someone uncomfortable.
The Col. asked me if he did his job and if I minded him in the section. Told the Col. he did his job well and was glad for what he contributed and that I had no problem and had never heard any of the other guys express any problems.
He stayed in the section and was still there when I rotated.
Seemed like the way to handle it. He did a good job and didn't offend so no big deal was made of it.
