As a veteran, I'm not opposed to women in combat, with one proviso -- the women have to meet the same physical fitness standards as the men serving in those combat units.

Currently, for a male Soldier age 17-21 those standards are (Minimums, to pass the physical training test):

59 push-ups in two minutes

58 sit-ups in two minutes

Running two miles in 16 minutes or less

For a female Soldier age 17-21 they are:

19 push-ups

37 sit-ups

Run two miles in 19 minutes or less.

Saletan places a lot of emphasis on assymetrical conflicts, but the fact remains that an Army unit can move only as fast as its slowest member, and can carry on average, much less combat materiel if it doesn't have a similar strength ability among all its members. No one is saying that women shouldn't be armed -- but can they be as effective on patrol as their male counterparts? Obviously not. They can't carry as much weight or move as fast.

Do away with the double standard. Otherwise, keep women out of combat units -- they are literally not fit to be there.
