Very simple resolution to the issue of women serving in the military. Make the physical standards test uniformly male. Drop the PT standards for females and allow them to perform to the male standards. It's called equality. When females are allowed to perform at physically inferior levels, why do we question the fact that it's fundamentally unfair and discriminatory?  One standard. 

Co-ed boot camps train to the female level. Road march paces are made to accommodate females. Group runs are made to accommodate females. Hand-to-hand combat training was nixed in the Army because of females. Go to any co-ed boot camp and take a look at the slowest run group. Females. Once we embrace equality for all, sexism dies a quick death. Perform to standard.
