On the card there are many not active objects. Mode of a distance of "AUTO"
doesn't join on not active objects. The distance of 1900 meters and lack of an opportunity to include "AUTO" in any situation, limits possibilities of the modern tank.
The modern tank is capable to shoot precisely on more than 1900 meters. Everything depends on that there is a tank or goes. There is a dependence of distance of an aim shot on shell type. For example tactical characteristics of the T-90 tank.
By rated estimates the battle range when firing straight off for armor-piercing ammunition of a 120-mm gun makes 1,9 — 2 km, for cumulative ammunition of 1,7 — 1,8 km. At delivery of fire from a place range increases, for armor-piercing ammunition of 120 mm 2,6 — 2,8 and for cumulative ammunition of 2 — 2,2 km.
There are also the managed shots of PTUR 9M119M "Invar", range of fire yes 5000 meters.
I cannot tell now for tactical characteristics of other models of the tank. They think have similar arms in an arsenal.
Sights in Arma3 tanks above than have no 1900 meters of correction of an aiming mark. There is no dependence on shell type. {F26243}
