If someone has submitted their release—let's say, it's a non-medical release—then they will get an appointment. They can request one with a release administrator and a transition adviser, and that's when the whole process starts. If it's a medical release and they are posted, perhaps, to the transition centre, then there is a slightly different but complementary process that brings them through the different steps as they transition out of the military as well.
