We know that a mortar blows upwards in a cone shape when coming almost straight down, but what would the blast shape be if it were lying on it's side?
One night while still with the artillery, the VC dropped mortars on our battery at the same time they hit one of the infantry units, they needed fire support so we fired the 105's on our hands and knees (trust me, not easy) during the mortar attack because we were afraid to stand up.
