intentionally so, as if still on his mission:

Sir, the barricades are secure and guarded. All approaches are clear for now. However…

He points at the map: There are three civilian coaches abandoned here on this street and one public bus here, the kind with two floors and an open top, I think it’s some type of tour bus, but I recommend we move them to form a barrier along here, and here, which will cut off the approaches to the side entrance here.

That way it will leave only a direct approach along this street here, and funnel any advance into a small, tight area we can more easily defend.

The Colonel looks up with a nod of approval: Good plan Lieutenant. Make it happen.
