What for?
What you're suggesting is, essentially, personal political power.
As if there's not enough warlordish tendencies in SE Asia - not
just with Indonesia, but also Thailand, Philippines & Myanmar.
Only S'pore & Malaysia adopted the British model within this
region.
The political "control" of the SAF machine is detailed in Huxley's
book, in the "Command & Control" chapter (I believe).
1stly, it's not a citizen army per se. 2ndly, any military
organization is never meant to be democratic. 3rdly, the military
is more concerned with policy-making, not Parliamentary feedback.
4thly, the SAF has actually institutionalized itself a lot from the
days when LKY, GKS, Lim Kim San & George Boogars (Perm Sec)
oversaw everything.
In the S'pore context, defence matters are very serious business -
FWIW only trusted people are allowed to participate & only
vetted representatives could gain insights via committees like the
GPCs. With the military itself, there's 3 channels of political
command: via the Defence Minister, a cabinet post (the SAF reports
to the CDF who reports to MINDEF); via the formal Defence Council
& via the Armed Forces Council (comprising cabinet ministers,
perm sec's & senior military officers). Their decisions tend to
be - luckily - objective cuz they only concern with policymaking,
rather than jostling for power/influence.
Even then, when criticism is due they're more associated with
over-bureaucratism & quantitativeness - whether in areas of
military ops/combat analysis ("scenario planning"), logistic
support/system acquisition, manpower planning, finance management
& crisis resolution (the Cable Car Rescue rebutted skeptics).
Not everyone like the idea of defence-experienced civil servants
posted to MINDEF or bonded scholars deployed in the SAF, of course
- ultimately all of them are indirectly "subservient" to the PAP
direction. But, on the other hand, the President now has certain
veto powers over military decisions &plus since the '80s, the
Defence Minister could not suka-suka appoint or fire senior
officers like before.
