Avigdor Kahalani is one of my heroes. I was amazed when the Merkava came out. I initially trained on the M60. We had a shoot off between my old M60A3 unit and one of the “new” M1 units. We outshot them stationary, but we weren’t even close to them when firing on the move.
I know Avigdor personally:-).And know prototype of Merkava even better;-).
Regarding firing on the move, gyroscope wins but mostly for short range targets.
