You should be worried less about the official response of the
SAF, than about the response of your own men. As you can see from
the responses on this forum, many still regard being homosexual as
something "wrong" in a cultural or moral context.
Singapore is still by far a patriarchal society. While the
government may be becoming more open, society in general still
refuses to accept non-standard behavior. If found out, you will be
the butt of jokes at camp. You will lose respect among your men.
Your men will be less likely to follow your orders and more likely
to question them. It will become taboo for your colleagues or men
to be seen with you outside of uniform. You will face
discrimination of the very worst kind and at the end of the day,
this will affect your productivity and the productivity of your
men.
As I mentioned, society in general does not accept you and the
military is by far one of our society's most conservative
institutions. Thus, on another note, if found out, the SAF might
not punish you openly, but they might make an effort to side line
you. Having a homosexual Major appearing in an The New Paper
expose, would still be a public relations disaster.
