I'm wary of those tank kill numbers not just for the propaganda influence, but also because Germans were horrible at telling Allied equipment apart so quite a few armoured vehicles might have turned into tanks. And in any case, against the brilliantly planned and executed Normandy Invasion, an unprecedented logistical feat, this was less than a bee sting.
Though being a member of the Leibstandarte Adolf Hitler doesn't exactly qualify him as a resistance member (that said, the leader of the Leibstandarte, Sepp Dietrich, knew about the plot against Hitler and was willing to change sides had it worked) he seems to have been a decent enough guy. There is lore about him that after a spectacular success at the Russian front, his superior awarded him a medal and asked if he could do anything else for him to which Wittmann is to have replied: "Yes, evacuate those three wounded Russian soldiers our medics had to leave behind under fire on that hill". Which was then supposedly done. I sincerely hope that really happened, it impresses me more than the umpteenth Allied tank destroyed.
