120mm mortar vs M777 155mm howitzer
The 120mm mortar is the heaviest fire-support weapon of many infantry units, with a maximum range of about 8 km using conventional ammunition. The M777 155mm howitzer reaches about 24.7 km with conventional ammunition, some three times as far. With assisted rounds, both can exceed these figures.
Both lines start at the same point. Each interval multiplies distance: this is not a trajectory or geographic route.
