All commissioned officers of Armed Forces, Police Force and
Civil Defence Force (havent seen swords from other Uniformed
Services yet) will recieved a ceremonial Sword. That is to say
ranks of Lieutenant (for SAF and SCDF) and Inspector (for SPF) and
above.
There marked differences in the swords. Instead of the gold/black
handle that SAF swords have, SCDF and SPF swords have a
silver/black handle. Another area is the sword tassel,
yellow/orange (SAF), blue/white (SPF) and red/orange (SCDF, i
think).
Another area is the sword guard for SAF (have no memories of the
SCDF/SPF swords), where officer's sword bears the nation arms,
while the Warrant Officer (WO) sword bears the warrant officer
insignia while Military Experts (ME) swords bears a national arms
on a pip.
Having said that, WOs (and Station Inspectors for SPF) do carry
ceremonial swords during parades. But there doesn't seem to any
stated protocol for them to draw their swords (There bears a
exception, but we arent going into that.)
That is your answer to the first question. Your next 2 questions, a
military style wedding means that you are own your own, to
find your officer kaki (usually, the NSFs are arrowed) to do this
job. Which means the drawing of Number 1 and its accessories is
subjected to availiability and approval. Not every senior officer
in the force wants a military style wedding, it looks cool, but it
is a hell of a job. Anyway, yes Police officers can opt for a
military style wedding too.
ANd your 3rd question has been more than satisfactorily
answered, i suppose.
