I don't think Palum was wrong per se, and it seems to me like you're just trying to go after one specific thing he said while ignoring a lot that he said was correct. And when he said "defensive", it reminded me of deep battle doctrine and the differences between Soviet/American views on it:
http://www.dtic.mil/dtic/tr/fulltext/u2/a258092.pdf
American doctrine and practice, embodied in the battlefield framework, treats deep battle as one of many components of a fight. Moreover, although we speak of the offense, American deep battle is primarily defensive in nature: The aim of deep battle is to prevent the enemy from massing, and to create opportunities for offensive action-"windows of opportunity"--that allow us to defeat him in detail.'
Of course I have no idea if that is what he meant, and there are a couple potential complaints here (one being timeframe of recognized US adoption of these type of tenets). But there is also the issue of the Germans having been fond of rushing to engage enemy armor then almost immediately retreating when they would come under fire. Allied armor would then give chase and run straight into the jaws of well prepared AT positions. After the AT guns would finish mopping the floor with the pursuing Allied tanks, the German armor would then turn around again and advance virtually unopposed.

Later the lieutenant colonel was asked a question about the use of tanks in action. He said:
The Germans towed their 88's behind their tanks. (Maybe they brought up 75's, or both; I know they brought up 88's.) They towed them up and dug in. Their tanks came out and attracted our attention, and, until we caught on to their tricks, the tanks led us right between the guns, got behind us, and gave us the works. We learned not to form the habit of going for the first 88's which shot at us. There were likely to be several much closer up. The first 88 that barked and the first tank were generally bait, and we had to refrain from plunging at them.
Again, I don't know what Palum meant, but there is also the impression that I've gathered over the years that in regards to US infantry and armor usage, is that if you are going to go on the assault at the very least...
LOL DIDN"T FUCKING FINISH
