For people so concerned about historical accuracy, you sure seem uninterested in the actual history of World War 2.
So, in the campaign, you play as Rousseau from the French Resistance (the Maquis). She's in the first image, and some of her accomplices (also in the game) are in the second.
Here are some actual photographs of the World War 2 Maquis.
This also applies to nations like Italy.
Now, your contention may be that Rousseau's listed as a leader in the Maquis. Well, let's go look up some information about an actual female Maquis soldier. This is about Nancy Wake, a British woman who was living in France, worked independently as a resistance member at first, escaped to Britain, trained, and airdropped back into France to continue her work with the French resistance.

It's possible no one called her Lieutenant Wake, but I think it's pretty clear she was serving in a leadership role.
