combat specialists pretty siong as you start from 3sg to 1sg.
cuz you go through sispec, then become sect.comdr then PS.
but after that, which may be about 3 years, you will be at least
1SG, then maybe go for CSM course etc...then relax abit liao...like
become CSM, or weapon specs, or go back to SISPEC etc....
if you need most money, ask the people there if RSAF specialist got
additional combat pay or not, if not, then i think combat spec got
slightly more money.
