Weapon inflation, perverse warfare:

I recall that the British Defence Ministry said within 48 hours after the hostilities had ended during the Kosovo war, that up to 90%, they said, of the the dropped anti-armour ammunition, has fallen for dummie tanks. The serbian corps back then retreated without noticable losses in armour and heavy weapons, and in a relatively intact condition - which made mockery of the intensity by which NATO air forces were attacking Serbian forces inside Kosovo.
It seems the russians are not perfecting the approach.
