That 4-5 also always included the MATSG staff and LSO school Marine if it was a Marine. For years it was 2 USMC CORE IP(Normally MAWTS/TG grads) at 106 with a Marine XO and MATSG CO/XO. Now there are 8-10 last I counted. A definite plus up. I think the premise had to do with what the squadron was putting out to the fleet in terms of Marine Cat I RPs vs what it was staffed to support in comparison to Navy manning at VMFAT-101 and navy throughput.
