As an infantry officer who served in Iraq, Afghanistan, and Guantanamo Bay, I have led men in combat and trained them on tactics and strategy. The mission of the infantry is to 'close with, and destroy, the enemy.' Our job, in a direct way, is to fight and win wars.

Combat duty is strenuous and physically demanding, and I'm not the first person to notice that men and women are built differently. And while many will argue that women will only be allowed into combat arms units under the same requirements as their male counterparts, count me as skeptical.

In the 360-degree battlefields of Iraq and Afghanistan, women have served honorably and fought valiantly. Yet there is a key difference between being in harm's way and reacting to enemy contact, and being in a direct combat operations role day in and day out. They are different scenarios that require different standards.
