BTW you did not make it clear you want these to be ARF MED, ARF HVY, ARF MED. You do not need these extra slots for people who are gonna be these ranks for 2 weeks max.
Just lower the perms to join trauma's unit, you have so much shit this is actually an insane ask icl.
You could even do this exact suggestion by making trauma's unit the default job for RANCOR, gives you all those ARF jobs you want for enlisted (except HVY)

They have an ARF subunit also why would you join the ARC BATTALION if you didn't wanna be arc?
