New battalion movie

I just opened up a window of youtube and it gave me some suggestions as usual. One of the suggestions had the word battalion in it and so I went looking on that topic.

There is a newer movie out about a women’s battalion formed in Russia or the USSR in WWI or WWII and based on true or real events?

They were a morale booster for the Soviets in WWII? How come I have not heard about this?
