If I remember correctly...
Other than the usual admin stuff, You will need to retake your
pyschometric test as the result only last for 3 years. The
interview will be short, but nothing much to be worried about.
After all that is done, you will need to take a first aid
course, pass your shooting and pass your IPPT. Showing
them result of IPPT from last reservisit is fine too. You will
retain your last held rank, and off you go to division, I
think...
Did I miss anything?
