Women were in World War II, serving many different positions and branches of the military for different countries, ranging from Nurses to front line soldiers, depending on the country. In many countries, such as Russia and the UK, women were even drafted into the military and Russian women fought on the front lines. Over 800,000 Russian women were in the military, mostly auxiliary units, while others served as snipers, aerial bombers, anti-aircraft and many other positions. Even in the USA, women served primarily as nurses but also in the Women's Army Auxiliary Corps, which later was converted into the Women's Army Corps and at one point was lead by an African American woman. They also fought overseas in the Pacific and European Theaters. ALSO there was the 6888th Central Postal Directory Battalion which was an all female all African American battalion that fought during WWII in England and France.
Then there's the blue facepaint that everyone's so uppity about. This one's actually pretty cool, though exaggerated for visual effect. One of the easiest places to see this used was with the 506th Parachute Infantry Regiment, 101st Airborne Division of the USA. These guys were nuts, and would often do "whatever it takes" to achieve victory and aid in the war effort. There were other units throughout the war that used facepaint, but this particular group was known for mohawks and multi colored face paint.
Then there's her prosthetic. It's actually pretty accurate to what was used during the war if they had lost the limb but wanted to continue service, as long as it wasn't their primary arm. So, that one's out too I guess. This one doesn't need much to answer for it, you can find it very easily with a google search of "prostheses arm ww2"
or you can click here for some information on it.
Then again, I'm sure many people no matter what you put in front of them are going to be upset that there's some representation of the people that were in the war, just to a slightly exaggerated extent, so that they would actually be seen. There's enough historical accuracy within it that I'm fine with it, as these groups of people were actually in the war.
