Besides communications and maybe a little bit of radar. What makes eee student better than mech student. Eee know nothing about aerodynamics. So no matter u are from which course. Most of the things u have to learn on the job. Things u learn in school doesn't really help much in DSTA as they are really in depth technology. I'm a mechanical undergrad in air system PC for 4 years and most non scholars here are from mech. Scholars needless to say, they will put them in this PC.
