Sure, but that wasn't one of your what-ifs. Yours was a list of worries about females in combat. Don't worry your pretty little head, if a woman joins (unlike you) and can do the job (unlike you), it will not reflect badly on your own shortcomings.
The Marine in the link has an opinion, and it's a fair concern that should be considered, and I'm sure those concerns will be by organizational higher-ups. Yes, I trust the proper decisions will be made, or corrected and refined as we learn as we go. I come from an Army perspective, and as the Marine noted, the Army is different and has "rogered up" to the tasking. Opening up a bunch of MOS positions that were male-only will not hurt the force.
