Oh, it's not going to convince you that Rommel lurks in town, but it will work to kick you in the teeth. Not following a scenario's guidelines as closely as possible usually results in a bunch of tanks and troops driving up behind your troops and beating them down. Or when a procession of French tanks drives through the killzone of a bunch of anti-tank guns in perfect formation. I don't know if this is just an AI glitch or the actual French style of battle. It could be lack of programming or a brilliant stroke of authenticity.
Supply usually becomes an issue at the worse times.
But not so close that they get destroyed by bombs or ambushes. A leapfrog approach works rather well, though it does wear down the armor. Depending on your tastes, running supply trucks back and forth may either be tremendously entertaining or horribly boring. I found it amusing. Hur hur hur.
