As a female player I would like to have female soldiers also in front line troops (before we start a discussion about this pls watch movies like "G.I. Jane" or think about the Russian Troops or the Female Resistance Fighters in World War II).
In OFP you was able to select a female soldier on the russion side, (sry have forgotten her name).
At least it would be nice to be possible to select a female voice like in Armed Assault (Voicename: Amy).
It would be a nice present for all the (5 :p) female players like me.
In ArmA 2 all Voices on highest pitch sounds like a man who lost his "best bodypart" :D.
