Bulky, but looks like I wouldn't want to be on the receiving end.
Holy jesus read this: Besides acting as a telescopic day and night sight, the computer has an integral laser range finder. When trained on a target, the laser can determine the distance to the objective, accurate to ± 50cm out to 500m and ± one meter over 1000m. When it has locked in the range, the computer relays the data to the fusing control system for the 20mm high explosive (HE) ammunition. This means that the HE shells can be timed to explode in an airburst after they have travelled the required distance. A soldier could therefore attack an opponent hiding in a trench by shooting over the top of it, or detonate rounds just inside a window that might conceal a sniper.
