There seems to be some confusion over two individual types of metal used in bombs to cause personnel casualties.
Bombs kill in any number of ways. One is concussion. The shock wave of a bomb destroys things, including flesh. Another is from splinters. The torn metal casing of the bomb deconstructs in the blast to make splinters. These metal splinters are of varying size and often do horrific damage by cutting and tearing as they fly through the air. Shrapnel is little metal balls that are included in the casing to add an increased volume of metal. They fly outward with the spinters from the metal casing, increasing the lethality of the bomb.
This picture shows the difference between splinter and shrapnel. They were found as part of the detrius of a Katyusha rocket fired by Hizbollah into Israel. This photo demonstrates the difference between shrapnel and splinter. The shrapnel are the little metal balls. The splinters are the jagged metal obects.
Either could be used against personnel or equipment. However, Hizbollah is using shrapnel in the Katyusha, an area weapon. These rockets are not being fired at military targets. They are being fired almost exclusively at cities to terrify and harrass.
