By referring to a bulldozer as military equipment, I am referring to the several thousand bulldozers that the federal and state governments have painted in funny camoflage paint with men and women in funny looking tan/grey/green uniforms driving them.
The national guard can take these bulldozers in time of emergency (or any other horizontal/vertical building equipment in the military inventory), and train civilians in using the equipment, providing contractors with a trained workforce in the area, instead of having contractors import workers from other areas (expensive), and instead of having people sitting on their front porch collecting welfare checks.
The federal government is probably very much involved in the reconstruction of New Orleans, but they shouldn't be. Federal involvement directly means that the state and local governments have fallen flat on their faces and been unable to accomplish the job. Federal involvement should be limited to monetary contributions. If the people of New Orleans don't want to lift a finger to help rebuild the place, let the Gulf and Mississippi river reclaim it.
