One thing that might be instructive here is to look at your special ops guys. Not a lot of ripped bodybuilder types, Fit and in great shape, stamina wise yes, but not superhuman strength, generally speaking. What makes them special is the will to push themselves to the limits, mentally and physically. Are there very many women who exhibit that will and the level of stamina required? Not many, I say, and those who have both of those and want to be spec ops, far fewer.
But they do exist, and they will join the units, and they will do fine. As long they make them meet the standards, and resist the forces that will insist that the women get a break, and the inevitable dries that applicants were cut for sexist reasons.
I am reminded of two women in two different ordnance shops I was in. One was a corn fed type from Iowa, close to six feet tall, and not willowy. The other was maybe 5'7", and slender, but not skinny. Given my choice of which one to help me lift my end of a 500lb bomb, the smaller of the two was my choice. Her focus and will was greater, letting her put more effective power out. The larger woman simply wanted to get it over with, and it showed.
