Well the wings badge in regs is (for pilot's) referred to specifically as the "Pilot's Flying Badge" or "Badge, Qualification, Pilot" in stores speak. Similar naming conventions apply to all "legacy" aircrew badges (Air Gunner, Loadmaster, etc) though the newer "generic Aircrew" single wing RAF badge is referred to as "Badge, Qualification, Brevet", which is, I suspect, a result of modern repurposing of the word Brevet as the use of language has evolved over time.
The good news is, for this particular measuring contest, it means you're both right....!
