The details contained in the autopsy indicate that this wasnt just random fire from some run-of-the-mill IDF terrorist, but from a sniper using rounds that are specifically designed to do the most damage and destruction as possible. The 5.56 rounds used by IDF ground troops are full metal jacketed that are not frangible, do not separate and do not leave fragments in the manner discovered in the autopsy. These types of rounds known as ball ammo are the result of various agreements by governments that stipulate that fragmenting bullets will not be used in the theatre of war so as to minimize the likelihood of death on the battlefield.
