- The M777 has an effective range of 14.9 miles firing regular artillery shells and 18.6 miles firing rocket-assisted shells.
- The Koalitsiya-SV is Russia's latest self-propelled howitzer. Koalitsiya-SV consists of a 152-millimeter howizter encased in a turret and fitted to a tank-like tracked chassis. It has a maximum firing range of 70 kilometers (43 miles)
- South African G6-52ER self-propelled howitzer using ammunition provided by the German/South African Rheinmetall-Denel Munition achieved a distance of 76.2 kilometers, or the equivalent of 47.3 miles link
So, is the military hoping that the 777 can be set up and moved, hidden from drones, and still have an effective hit rate over something that can fire 30 miles farther away? Self propelled, you fire and move right? Eliminates the enemies ability to get a tangent on your ass and counter fire?
What am I missing? Is it the not having to worry about a tranny going out on a pulled 777 vs a self propelled?
Easier to hide in an urban environment?
