BATTLE WOUNDING CRITERIA MADE EASY "Lethality"

"A fragmentation device should ideally produce as many lethal fragments as possible to make the target incapable as early as possible. A device which meets this requirement is said to have good 'lethalithy'.The most severe criterion requires the incapacitation, within 30 seconds of the strike, of a determined well protected target occupying a good defensive position. Another criterion is the 'Assault 5 Minutes Criterion'. This requires the incapacitation of a highly motivated assaulting infantryman in five minutes."
