Who knows if this is true, I suspect it is, but I’m willing to be a little skeptical.
If it is true, if the war goes on for another 12-18 months under the current conditions, Ukraine will no longer exist except in name only, as you say, the men are rapidly running out, throw women into the battle and they will only get killed quicker.
Maybe the prospect of seeing thousands of women getting killed, will bring enough sanity to people and force them to negotiate an end to this charade.
Meanwhile Russian women are trying to find out what happened to their husbands, brothers, sons and boyfriends.
