Hi, is there any JPSDS signed on out there that can tell me whether i can still opt to other units before i enlist after i signed?
Yes you can choose which vocation you're interested in, then they will allocate you your unit after training. But of course i don't think you can choose commando's etc, not very sure bout the Army part, but at least for Airforce and Navy, you can choose to be technicians etc.. After that camp, unit/squadrons is out of your control.
Alright. but what if i already choose the vocation but i wanna opt to others after i signed. can i?
Nope, i don't think you can..Unless you happened to know some big shot in the SAF.. But i will guess they won't allow you to.
