When AI is gunner of a Scorcher M4 unit, it will refuse with a 'Cannot execute, adjust coordinates' to fire at distances from approximately 13.3 km to 14.5 km distance from the unit. No matter what type of ammo is selected. Shooting at distances less than 13.3 km is no problem. As well as distances above 14.5 km. It seems like some kind of exclusion zone. When a player is in gunner position, shooting at the 'exclusion zone' works.
