Nothing stopping these departments/units/ministries/forces from using chartered buses to move their personnel for non-official purposes...

Airforce/TUDM can do, why others cannot? Budget tarak ka?

Army also I see he drive slow slow and when used unofficially it's usually used for shifting personnel with their house furniture... if Army lorry enter highway usually got convoy...

Ini FRU perasaan Federal kuasa besar so ingat tak yah kisah kot... nanti sudah upcar pulak.
