Really helpful thanks and on the second point its when pinching. One unit is engadged on the front and the side once the center unit that was pinched dies how should the one attacking from the side move. Dosnt have to be pinching just side attacking really
Units will move to get to the closest opponent in their front arc (or the closest opponent behind them if nothing is in their front arc). This can involve a regular move, a turn, sideways movement, a reverse, a reform, or a combination thereof--whatever gets them the closest. (Or, if another enemy unit is within final rush range the unit will just final rush.)
