Armored Cav Regiments didn't get patches until the 1960's, I believe. I know when my dad was in Germany in the late 50's/early 60's with the 11th ACR they wore the 7th Army ("Seven Steps to Hell") patch.
When he deployed to Vietnam in 1966 I believe they had the Blackhorse patch by then. So a WWII era soldier would not have an ACR patch of any kind.
Marty, at least the 2nd, 3rd and 14th ACRs had their patches in 50s, while not worn on the Ike Class As, they wear worn as pocket patches in a manner of speaking on fatique items, some but not all wore them on the pockets and also above the U.S. ARMY tape, with the 7th Army patch worn on the sholder. This practice countiued till around 1967 when these patches were then allowed to be worn as shoulder patches. But your right on the 11th ACR, seem,s they got their famous Blackhorse patch sometime in the 60s.
see here for a 1955 example of the 2nd ACR,as well as a 6th ACR, and here for another 50s 6th ACR item
Below is troops of the 3rd ACR, Bamberg 1956 with a least one guy wearing the Brave Rifles patch. There's other topic floating around about these units showing the patches worn above the tapes.
