After BMT Recourse, Return to Unit (RTU) OR New Vocation?

chickennugget SG

I am wondering if it is possible to be revocated to another vocation when going back for BMT Recourse IF i passed Driving course?

I was posted as a driver trainee .

I ooc'ed from BMT and have been in my unit for a few months so I am also wondering if this is my permanent unit (and thus have to RTU)? Or is this considered a temporary unit for me?
