I think these are really moral choices of a nation. (and perhaps should not be so much of a gender comparison.)
Is it morally right to put a woman on the front-lines as a child bearing person?
Would an honorable woman fight next to a man in the name of self-defense probably yes. If a man was available instead would that be better?
Is it right to place a gay man next to another man that is under great duress or loneliness in a war situation?
When is war justifiable, that any man is exposed to those situations?
If you have a high suicide rate among the existing military is it right to impose a new moral choice on that army?
Why do you have a high suicide rate already, what is the nation doing wrong now?
Sending young men from divorced homes and a country with high abortion rates into a high male dominated society is there a link to suicides or is the war not justifiable?
The Moral choices of a nation are probably what is the important part. (i.e. Nazi Germany choices, US dropping nuclear bombs on citizens in WWII and why we don't do it anymore.)
