Re:Air Medals and Oak Leaf Clusters
A bit later, but my experience with Air Medals was that for actually getting stuff, in my squadron when one was awarded the first Air Medal you received the medal and the award certificate. The unit then saved up until you had earned five more and then you got a certificate (only) for each five clusters. When you rotated home you were submitted for whatever odd number of clusters you had received since your last five-cluster certificate and got one certificate for them. As for the actual clusters, I bought them at the exchange.
In the late 1960s, there were folks with lots of Air Medals. The Navy wound up replacing their stars (the Navy equivalent of Army and Air Force clusters) with numerals on the ribbon. The Air Force put a limit of four clusters of any kind on a ribbon (not the medal) and authorizing wear of a second ribbon to hold other clusters -- but the second ribbon counted. So someone with ten Air Medals would wear one ribbon with a silver cluster (6 awards) and a second ribbon with three bronze clusters (4 more awards).
Push the stick forward, the houses get bigger. Pull the stick back, the houses get smaller (unless you keep pulling -- then they get bigger again)
