The warrior culture generally refers to those values that were assumed to be essential to operational effectiveness, especially in the combat arms domain: assumptions that women and men are different; men are strong, women are weak; women are protected, men protect women; women are emotionally unstable, men are more stable for fighting in war; that sort of thing. Up until 1989 when the Canadian Human Rights Tribunal said that women would be integrated into all environments and roles, the warrior culture and the values associated with an all-male environment were held as essential to combat effectiveness. We've learned since then that the all-male domain is not essential, but there are still strong values related to that, I would say, especially in the land combat arms.
