If it's a CQ program, there is a schedule of required re-training events based on how long you've been gone. I'd call your type training mgr.

Greater than one year will typically require some dedicated ground (probably one-on-one unless there's more than one of you returning) and a couple practice sim sessions followed by normal CQ footprint.

Less than one year they might be able to just do CQ but I imagine they would give you at least one courtesy warm-up sim.
