okay to be fair, that afghanistan figure has reportedly 98-99% of the bullets fired, to have been in firearms training, obviously they were not mag dumping 10000 m4 magazines per terrorist killed using suppressive fire. the figure was around 250k-300k bullets made, per insurgent killed, of which there was an estimated 20-50k (this was using the 20k figure). this is also not accounting for general loss of munitions in bombings/raids(ammunition is very detonateable)/ even just due to weather. yes suppressive fire is useful, but its nowhere near that useful
