I agree with the forum members about the 50,000 round stat(which includes squad automatic weapons, aircraft systems, armor, etc). The book states that military snipers & sharpshooters had a EKIA rate of about 1.4 rounds per enemy dead.
Years ago, I saw & read how JFK's SECDEF; Robert Macnamera(check spelling) was angry over US armed forces in SE Asia not "killing enough" NVA & Viet Kong. He was a business exec for Ford & thought you could apply logistics(weapons troops ammunition) and expect results. Real combat(killing & dying) is not a business model. It's bloody, dangerous & stressful.
