Yeah, it's appalling that they weren't getting recognition for fighting on the frontline. As for militaries with women on the frontline, both the Kiwis and the Canadians have had a handful of women in Combat Arms Corps like Artillery and Infantry (like Cpt. Goddard, whom I mentioned in the OP). The articles in the OP that I've linked at the bottom illustrate why there'll only ever be a very, very small number.
For a lot of militaries it's simply a high cost for not a lot of gain, since women are injured and fail infantry training at a disproportionately high rate to men. This would probably be mitigated by a specialist physical training program before the commencement of Infantry training, but again, this is a large cost for little gain until we can change the structure of the female body.
Pavlichenko was no doubt a good sniper, but she's useful for highlighting the issues with the female body in combat. And that is that there's no doubt women can function in combat (the psychological arguments are bull****, women are in combat every day outside the wire in the Middle East and there's no 'oh god save the wimminz' going on there). The issue is with the female body's ability to bear a load for long periods at a time, move at a combat pace with her load, and maintain enough of a physical capability to do her job whilst on operations, which are things Pavlichenko would not have been doing as a sniper, or at least, not with the kind of loads that our people are carrying today.
