It doesn't seem to be the Font RSAF normally use on their plane
and they are at the wrong location.
DCC are usually way lower.
So i think they are Photoshopped.
As for WOSE piloting aircrafts and comparison with US Army... there
are few points we have to note before we make comparisions.
US WOs are Commissioned. They hold the President's Commission and
in US, the definition of holding a commission is clear. Their WOs
receive intensive flight training equal to that a helo pilot will
get. However they cannot get Officer rank as they are only really
specialised in Helo flying and related operations.
A US Pilot officer on the other hand are trained much more other
aspects than flying only. In US context, a Warrant Officer is an
Officer who are Specialist (trained intensively in one area). Where
as an Commission Officer is a Generalist (globally trainied)
To hold a commission in US means they are authorised to act on the
President's behalf using the powers as vested in them by the
president.
in SAF, i do not think there was ever a formal definition to what
"Commissioned by the President" means. SAF WOs are simply
Specialists who have obtained minimum 10 years experience and went
to further training to become WOs.
SAF WOs do not hold a commission.
