Yep incomplete errata counters. 12SS is wrong color. No Horrocks is quite an oversight. JY said the 17SS recon should be a 5 combat strength company and a 4 strength company. So the errata counters need errata.
Actually didn't include Horrocks because it is my belief (as born out in Market Garden) that he had lost the "fire" after being wounded in N. Africa and convalesced. He was better than the guy he replaced (off hand can't remember) and a solid commander - but nothing spectacular. Hence no leader counter for him.
