When I was in the Army, the issue was always raised by female commissioned officers. You see, the majority of the General Officer slots are combat arms, from which the females were barred. I doubt that very many enlisted women want to be in the Infantry or other combat arm, but the officers want their opportunity to wear stars on their hats.
The one possibility I can see is changing the Army Physical Fitness Test scoring from male/female with steps for age ranges to Combat Arms, Combat Support Arms and Combat Service Support Arms.
A battalion commander buddy of mine was chosen to host their latest fun visit and was worried sick about what to do. I told him to just let the ladies spend a full day on an artillery gun section (we had M-198 155mm howitzers) and work in the gun crew's positions. He did exactly that: they wore the helmets and flak jackets in 29 Palms' sweltering heat, they helped emplace and displace the howitzer (all 7 1/2 tons of it), helped unload section gear and spread the camo nets,and helped load and fire about 80 rounds of 96 pound M107 HE. Big day for them but the charm wore off within minutes and towards the middle of of the day were asking, nay pleading, to be taken out of the fun to go home.
Needless to say, their report agreed whole-heartedly that artillery firing sections were too intense for women.
Guess we have to learn those lessons all over again, don't we?
