I don't know -- but they mean WOUNDS, NOT scratches.
Can you imagine what would happen if everyone would start reporting scratches, which only require a bandaid?
Band-aids are most certainly a major military expense item. I'm confident that a close examination of the line item budget for the military would reveal that band-aids cost the taxpayer in excess of $10,000 annually.
Now I don't know about you, but I don't want every soldier, sailor, marine and coastguardsperson going around willy-nilly and bandaging every little scratch, pimple and hangnail.
The only way to control excessive band-aid use is to require voluminous paperwork reporting of every "wound". Those deemed serious enough, such as grains of rice forcibly mashed into one's posterior region by a grenade explosion, should warrant a band-aid and a Purple Heart.

LOL - I'm just remembering all of the times that I (and others) got beat up, bruised up, and cut up during refueling in the Navy (forward refueling, Adams class can, Indian Ocean). I received more injuries during refueling than Kerry got in Vietnam!
WIA, KIA & damage to assets would be reported immediately via spot report (i.e., by those on the scene, before leaving or in transit from the scene).
