If they wanted to be representative of the "diversity of the US military", they'd keep the dominantly male character models.
- Statistically, still around 98-99% of casualties of war are male, precisely because the more dangerous roles, like you'd see in Call of Duty, are performed almost exclusively by males. Is that discrimination? Well, against whom, exactly? The male gender, who's lives are considered more expendable? Or the females who want to be treated as true equals, but have difficulty advancing due to lack of combat experience?
Anyway, though, despite the irritating PR spin, I'm glad that gaming is becoming more inclusive.
