America has been creeping closer and closer to allowing women in combat, so Wednesday's news that the decision has now been made is not a surprise. It appears that female soldiers will be allowed on the battlefield but not in the infantry. Yet it is a distinction without much difference: Infantry units serve side-by-side in combat with artillery, engineers, drivers, medics and others who will likely now include women. The Pentagon would do well to consider realities of life in combat as it pushes to mix men and women on the battlefield.

Many articles have been written regarding the relative strength of women and the possible effects on morale of introducing women into all-male units. Less attention has been paid to another aspect: the absolutely dreadful conditions under which grunts live during war.

Most people seem to believe that the wars in Iraq and Afghanistan have merely involved driving out of a forward operating base, patrolling the streets, maybe getting in a quick firefight, and then returning to the forward operating base and its separate shower facilities and chow hall. The reality of modern infantry combat, at least the portion I saw, bore little resemblance to this sanitized view.

I served in the 2003 invasion of Iraq as a Marine infantry squad leader. We rode into war crammed in the back of amphibious assault vehicles. They are designed to hold roughly 15 Marines snugly; due to maintenance issues, by the end of the invasion we had as many as 25 men stuffed into the back. Marines were forced to sit, in full gear, on each other's laps and in contorted positions for hours on end. That was the least of our problems.

The invasion was a blitzkrieg. The goal was to move as fast to Baghdad as possible. The column would not stop for a lance corporal, sergeant, lieutenant, or even a company commander to go to the restroom. Sometimes we spent over 48 hours on the move without exiting the vehicles. We were forced to urinate in empty water bottles inches from our comrades.
