Well in St-Jean the reg force (all 3 elements) IAP PO103 involves your taskings (doing up your orders and accomplishing such missions as - make a rope bridge, make a first aid station, etc). It tests your ability to lead a section in the field and accomplishing a mission. This PO is then expanded on during the BOTP course (more details in the orders, harder missions, etc).
I assume you are talking about Navy Reserve IAP, and from what I have been led to believe, the Navy follows the same PO's and training as the Reg F. Hope this helps. I may have a list of POs kicking around if you want to send me a message.
