Alright, lets say that all else remains constant in terms of the
equipment, Arty caliber say 155mm, shells used is High Explosive.
Read that the "effective" blast is approx. 100m, so lets say that 2
salvos of 4 rounds from 4 guns are fired, is there a high chance
for the rounds to all land within the same area? Given that a
competent FO is tasked to watch the fall of the rounds?
