A pack is required for PO (level 2)In order to go SWAT (level3), you have to already be PO.So, If you wish to go SWAT, and choose a character with no pack (like Road Block Captain V.2) , you still have to have a pack, because you cannot go SWAT until you have been approved as PO. And in order to be PO, you have to have a pack. But you do not have to wear the pack. You cannot go from Level 1 to Level 3. You have to go in order.If you could go SWAT without a pack, I would have already done this years ago.
