I know all nations made use of women as part of their labour forces due to the shortage of men. While, I am also aware that many nations had separate women's units in their armed forces. However, these units appeared to have support roles as opposed to combat roles. I also know that the Soviets did use women in certain combat roles, such as snipers. Besides this, are there any other cases of women fighting on the front line?
Only focusing on the Soviets, which you seem to already be somewhat informed on, but nevertheless, this previous answer might be of use for you.
