It all depends on you.RMS clerk is a important part of the CSS and "F esch" team.It's been said that an army walks on it's stomac(sp),but in the CF we walk on paper!
If your really interested,you might want to talk to someone in regards to your progression.Since your currently in university,your limited to summertime for continous employment.The RMS QL3 may only be offered during this time,and if you have to do the SQ during the summer,this could prolong your wait to be 3's qualified.If not,than have at er!
One thing I've noticed,is that in the reserves people tend to do different jobs than that of thier civvy carrer choice in order to live the adventure on the weekends,and to pay the bills during the week(My old Adj said this-He was a crown lawyer civy side and a officer in the Artillery part time).I noticed this alot when talking to a friend who was a medic.I said to him"How come your not a paramedic?"and to this he replied"I like having both worlds"(he was a steamfitter).
So food for thought.
