[PatG]

If the AI's or your opponent's infantry is popping off at max range - you are being given a gift. A couple of refinements. Use tanks especially Shermans, early Mk IV with short 75mm, StuG/Hs and/or infantry guns. Killing MGs and rifle infantry is what they were designed to do. Second, use smoke to blind the infantry, then move up close while adding a little HE on the opposition then when the smoke clears you are at short range against a supressed enemy.

Concerning scouts, I will usually set their firing range to 1 hex - sometimes a little more. Using one hex per turn advance rates and/or cover you can usually get scout units very close to the enemy and pinpoint their positions. The short range also prevents your scout from revealing themselves through op fire and allows you to select when to use them to suppress.
