You can pan out or zoom in, or go in low and look down the ranks. Here, long lines of bishops and infantry are poised to march forward. Pieces can move together to the extent that they have a move in common. In this case, the bishops and infantry can both move diagonally one space forward. They can move in a single formation as long as an unbroken line links one piece to the next. Conceivably, on these six boards all 96 infantrymen can move forward with all 24 bishops as a single fighting unit.
