Questions that come to mind:

1) Why did we move troops in before fortifications were complete?

2) We must have figured this was a vital location. Why didn't we know the "lay of the land" and have local contacts before moving troops in?

3) Who gave the terrorists advanced notice that we were coming?

4) Did they force the villagers from their homes or did the villagers cooperate with them?

4) ...insurgents had fired "with small arms, machine guns, rocket-propelled grenades and mortars using homes, shops and the mosque in the village of Wanat for cover."

1) Why did we move troops in before fortifications were complete?

The infantry usually isn't able to call ahead for reservations. When an infantry platoon, the 45 U.S. soldiers, decides to occupy a location, they dig their own fighting positions with an entrenching tool, aka an E-tool, along a perimeter with respect to the terrain.
