Re: Why did you add woman to battlefield 5
Ask any russian about the Night Witches air squadron, their women snipers or tankers (yes they've fought in tanks in various roles, not only as drivers, but gunners, tank commanders and so on).
Also, check the Resistance movements all over Europe.
Intelligence Service and SOE, OSS and the canadians trained at Camp X sent women agents in the occupied Europe to carry sabotage acts and even fight if necessary.
So while, uncommon in the Western Europe (exception being the French Resistance), women on the Eastern Front weren't a rare sight.
The woman depicted in the trailer seems to be a resistance fighter (or maybe an agent) and not a regular soldier. So, i see nothing wrong with that.
Plus...not every game needs to be historically accurate. Sometimes we can have fun without that.
