I was thinking about the physics of a tank firing while moving over uneven ground, and had the following idea, which is at least partially supported by Jentz's data (14% accuracy when moving toward the target from 900 to 600 yards, 33% accuracy when moving perpendicular at 650 yards [albeit at higher speed]): Tanks moving at speed may be more accurate when firing perpendicular to their direction of movement.
Assuming that the majority of a tank's motion while moving at high speed consists of forward/backward rocking, the greatest motion of the gun would occur when firing in the same direction of motion. Conversely, the angular rotation of the gun would be minimized when firing at a right angle to the direction of vehicle motion, thus (theoretically) minimizing the effect of vehicle motion on firing accuracy. Of course this would depend on the suspension and the relationship between the gun's location and the center of vehicle mass, but (at least in my uninformed mind) the motion affecting the gun would be less than firing forward. Thoughts, comments?
