Laurent - 'Ensign' in USN is exactly the same as '2nd Lt' in USAAF or USMC.

Flight Officer (F/O) is Highest Enlisted rank in this case for the USAAF, but about the same as the current rank of Warrant Officer in the gray area between Officer and NCO's . The USMC actually permitted some NCO's at rank of Sargent in early days of WWII to pilot fighters but it was rare.

The USMC ranks and names for officers are identical to USAAF and USAF whereas the USN does it's 'own thing'
