I wouldn’t think they would be the best vehicle for this purpose because they wouldn’t fragment. A tank would be a poor choice as well.

The Humvee is not armored.

The aluminum body reduces weight and provides resistance to corrosion. Aluminum body panels are riveted and bonded together with technologically-advanced adhesives to provide additional strength. The body is designed to flex to accommodate off-road stresses.
