Now that this thread has been necrobumped, can we expand the question to the other Services? My best understanding is that FAA FJ squadrons still had Lt Cdr COs until some point in the 1980s, and all (?) Army Air Corps squadrons are commanded by Majors. Is the latter because an Army squadron is a smaller unit, being the equivalent of a Cavalry squadron which is akin to an Infantry company, and adminstratively part of an AAC regiment (which is confusingly equivalent to an Infantry batallion which is smaller than a regiment)? Or is it just that they've avoided rank inflation longer than the rest?
