The ME scheme is not between but alongside. ME4 = LTA, ME3 =
MSG.
And I think all ME are regulars. Never hear of NSF becoming ME.
So although there may be confusion about who theoretically outranks
who, in practice any ME (except maybe ME1 or ME2) will outrank the
NSF.
Yep you are right, the ME scheme is alongside the WOSpec and
Officer schemes. However, a slight correction, ME3 = 3WO to 1WO.
MSG equivalent is ME2. ME4 = LTA & CPT.
All ME are regulars. A newly minted ME1 out of training is
equivalent to a 3SG. Likewise, on the ground, an ME3 - WO
equivalent - still gives the due respect to his PC who could be a
ME4 or NSF 2LT. From my observation, the issue on 'outranking' is
not really emphasised as much in today's SAF. I have observed a
regular LTA address an ME4 as 'Sir', likewise I have observed an
ME4 (PC appointment) address his fellow ME4 (OC appointment) as
'Sir', too.
In practice, it is more important to respect each other's
appointment and place within the organisation :)
