I'll right I will go into more detail. 120 with a thirty inch step works fine when you're marching in a straight line but nothing including parade review is in a straight line. When the maneuvering element is on the march and a move to a ninety degree angle in a uniform manner is needed the proper command is "column right... march". It's a two part command with column right being the preparatory command and march being the execution command. On the command march the element leader and guide execute a movement of pivot with the element leader taking 24 inch strides
the guide marches ahead with 30 inch strides
so he over takes the element leader. The rest of the column pivots where the guide did but if the entire column kept taking 30 inch strides they couldn't maintain cover, alignment nor 40 inches back to chest.
It's like runners running around a track, the distance the outside squads of the column have to travel further so they maintain a 30 inch stride
the inside squads of the column must shorten their stride so cover and alignment and distance may be retained so the inside most element cuts their stride to 12 inches
but maintain cadence by lifting the legs higher. The next squad from the inside also shortens their stride but to maintain cover, alignment, and distance the cut their stride to 15 inch strides
but maintain cadence by lifting their knees higher than the outside of the column but not as high as the inside of the column. This way the outer most squads can cover more ground than the inner most squads and still maintain cover, alignment, and 40 inches back to chest.
It's easy if you don't confuse stride with cadence.
