Sounds like a lot of ammo, but, do the math....
Killer Instinct; How Many Soldiers Actually Fired Their Weapons in Past Wars & How Has Simulation & Other Training Helped?
Published January 28, 2018
During World War II it was estimated that 45,000 rounds of small arms ammunition was fired to kill one enemy soldier. In Vietnam the American military establishment consumed an estimated 50,000 rounds of ammunition for every enemy killed. Small arms ammunition includes the ammunition used by the sidearm, assault rifle, rifle and heavy machines. Currently in the US inventory it would be 9 x19mm, 5.56 x 45mm, 7.62 x 51 mm and 12.7 x 99 mm. Pistol through the venerable āMa Deuceā, M2 50 caliber Browning Heavy Machine gun. You could probably perhaps include the 40mm grenade launcher too.
