Not sure about the Army but in the Air Force a Silver Oak Leaf cluster represents 5 awards and the Bronze Oak Leaf Cluster represents one. Now that I think about it, the medal would only be one with two Silver Oak Leaf clusters and the “V” device.
I believe the Army and Air Force have the same criteria. Navy and Marine Corps call it a “Combat V” (instead of the USA/USAF “Valor Device”) and issue stars instead of oak leaf clusters for subsequent awards of the BSM.
