Admittedly the tanks of this period not having laser range finders is a good example of why you'd want a .50 coax for ATGM suppression. Walking your shots with MG tracers to hose down an area is probably a bit faster than the manual procedure to estimate range for the main gun. And a few seconds might make the difference between eating a sagger or getting the operator to blink or flinch.
