The reason the Marine Corps works is because right from get go, everything "normal" is stripped away. The Marine Corps (all mil imo) is no place for social experiments.
The only thing that our military needs to focus on is, what makes us more lethal PERIOD, FULL STOP.
The Marine Corps Mission is to, locate close with and DESTROY the enemy with fire and maneuver.
Male and Female recruits have NO PLACE for one another.
