Well stated. Since the National Commander approves the AL Riders program on a state by state basis, the rules for types of patches and rockers and their placement can be found in the Rider's Manual for your State.
I have read the manual for Florida, but haven't compared it to the rest of them.
Apparently the OP, IATRIKEBOB, lives in Iowa, so for his benefit and enlightenment, I hereby present a link to the American Legion of Iowa, Rider's section:

(I still don't see what all of the fuss is about)
