I was going through my grandfathers album of stuff he had put together after the war, and came across a patch I can't seem to identify. I know he was with the 16th Armor and he has that patch, but next to it is an armored patch, (tri colored triangle) but instead of a number it appears to have an "S" where the number would be. I will try to get a picture next time I have access to it. Thanks for any help!
