You are aware that there are many different types of payloads that the Tomahawk can deliver? Right? I'm sure there was a combination of munitions delivered.
I wonder how beautiful you would think cluster/fascam munitions are if you ever drove a 5 Ton dump truck over one that failed to detonate. Personally, I abhor fascam munitions.
Cluster munitions are the best choice for destroying planes and fuel tanks on an airbase.
As far as driving a truck over a UXB goes, I will not be returning to Southwest Asia any time soon. If I ever return to that area, I will let you know if I drive over one of our bombs.
