You think it is so easy???
First thing MY do not have much arty pieces , 2nd thing is that if
any large movement of troop including asset like armour and arty
units could not be undetectable by satellite becos such large scale
movement is practically impossible to hide, 3rd thing when
something is going on, there will always be a lot of electronics
traffic , that is inevitable for any large scale mobilisation.
Lastly , you better hope you dun hit any US and ANZAC forces in
SG!!!!! 
Unless you could take out all our airfields and all the emergency
runways, there will alway be sufficient a/c to bomb the hell out
any troop concentration.
As for Yom Kippur war, Israeli actually detected the large troop
concentartion over in Egypt border but they assumed it as one those
training exe, but SG have learn that lesson , many years ago, we
detected that the MY and Indon will be airdropping troops over
Johor inan exe and we get into high alert likewise the time where
Israeli PM visits, so we could certainly have the mean to do so, it
was reported that we have one of the most sophisticated Intel asset
in SEA or is it Asia.
So only way MY could be successful in immobilise us is that we
totally unable to detect such sneak attack!!!
So is it possible???
Does MY want to risk it since SG have both qty as well quality
advantage in all asset????
Becos the table could turn around very badly for MY!!!!
If all thing fail, we still have US becos we are afterall almost
like a non-NATO ally of US , it will be big mistake for MY to try
anything funny becos MY might end up like Iraq!!!!!
