Well, to be technical, no I wasn't in a combat arms unit. Those are infantry, tanks, and artillery only. Was I in combat though? Yeah, I was a machine gunner for convoys during the Surge.
Personally I think it's a bad idea so long as you have different standards from women and men (specifically, lower standards for women). I know both from history and personal experience that there are some women who are capable of doing the job just as fine as any man who has walked the Earth, but they're the exception, not the rule (in my experience). Additionally, you have a bunch of potential problems adding them to the mix. For example, my squad was the only one without a woman in it when I deployed and my squad was also the only one that never had someone down each month due to menstrual cycles.
It's going to be very challenging for combat roles to integrate women. Not that it cannot, or should not, be done, but it will be difficult in the extreme.
