I could see it working early on when they were up against the Italians with their light tanks and infantry, but not later on against the Afrika Korps and their heavier armour, better gunned tanks and effective anti-armour guns and tactics.
I can imagine them getting around the open flank of infantry in the line or a rear echelon formation, coming at them from their rear. Then run in gunning everything in sight while racing around getting and sending the intel, and dashing off over the horizon. That would work for lightly armoured scout cars.
Still, it sounded like 'desperate times call for desperate measures' that not many would be up to doing, and those were desperate times. For that, I had and have the greatest respect for them.
