They should be using the SAS Model that the Brits used in NI
snipers in the badlands, that way you setup a couple of days ahead of a likely spot on a rooftop etc then a .50 into the body that will go thru any armoured vest. Gaza presents more of a challenge but an infiltration with a hard extraction team waiting on hand for the sniper and his spotter should work while minimising civilian casualties.
