There are basically two types of airforce personnels - pilots and ground crews. Basically for the pilots their trainings are of course more stringent but they also need a certain qualification/credits from their studies to make it. Most people make it to the airforce by just being a ground crew or maybe an airborne trooper. The Royal Malaysian Air Force elites are known as PASKAU (Pasukan Khas Udara), something like the SEALs in the US.

Salary in the military are different as they pay according to ranks, no matter whether you are a ground crew or a pilot. They of course do not have flying allowances like the commercial pilots

Not very sure and do not know whether the above is accurate or not since I was from ROTU Navy and I hear bits and pieces for Army and Air Force stories... Anyone from the Air Force here?
