I agree with what equlus84 said. SAF probably will want a
multi-role air/land/sea capable Rapid Response Force consisting of
regulars, which they may form taking elements from existing units
(commandos, Guards, NDU etc) don't know what they'll call it. We
probably don't need marines for war against our neighbour in the
north, but if we have to fight against other countries, marines
would be useful, since you have to cross a sea.
Another question, if they form the marines, is how far are they
going to go with it. If we are going the indonesian way, then you
don't need much in terms of vehicles and ships (we already have
them). But to go big-time seriously (such as middle powers like the
Spaniards and Italians with naval task forces), you need:
1. Dedicated vehicles such as AAV (Amphibious Assault Vehicle) and
hovercraft - Bionix/Ultras won't do, need something capable of
going from ship to shore in all sea states, day/night and
speedily.
2. Ships - at least 2 LPDs much larger than Endurance class (>
15,000 tons). Marines typically have multiple means of insertion -
via sea or air. So, the LPDs should be able to handle several Super
Pumas or even Chinooks at one time to launch a substantial force
(not one at a time like our LSTs). Also, since our 4 LSTs are not
always availble (transporting for the army in overseas
deployments), we need dedicated LPDs solely for Marines so they can
be deployed anytime.
3. Destroyers/frigates and subs to escort these LPDs (perform
anti-submarine, anti-air, anti-ship roles). Currently if deploying
in bluewater, only our stealth Frigates and subs can fill this
role.
4. Resupply ships. In US Marines task forces, you have
replenishment ships to carry anything from fuel to ammo and food. A
foreign analyst of RSN says RSN won't acquire resupply vessels due
to the implied nature of their role - too offensive, for
force-projection only.
A more realistic goal may be to follow the Australians. They are
acquiring 2 Mistral Class LPDs (from DCN): 21,300tons "amphibious
assault, command and power projection ships" by 2012.
