Accuracy can be overstated, though. U.S. infantry was trained to shoot aimed fire when it arrived in Europe in '42-'43. The semi-auto Garand rifle had twice the practical rate of fire of bolt-action rifles and this required increased fire discipline because of limited ammunition.
The infantrymen didn't see much of their enemies on the battlefield, though. Consequently, they shot less and were often suppressed. In the end, they had to be allowed to be more active and shoot into the general direction of the enemy, through concealment and inadequate cover.
My greatest concern with suppression is that at times you might not even guess the general direction of incoming fire right because you're not prepared to expect fire from all directions. That's most of the trick behind parapet and flanking fighting positions, after all.
I remember a report of an infantry regiment's river crossing in France. The river crossing's success was delayed for half an hour with many losses by a single light machine gun which was well-sited in a building for flanking fire along the river. They simply didn't identify that fighting position until the third or fourth attempt or so (I have no clue why the flanking nature of the fire wasn't obvious because of the small fountains on the water surface.)
