Yeah, that's the general idea. Three groups of people:

- Players who have played Planetside for a bit and are in the outfit can just join a squad and get gaming.
- Players who have played Planetside before but are not in the outfit, should go to the welcome platoon to get an invite, and then hop on over to one of the squads.
-Players who are new to Planetside should come to the welcome platoon for an outfit invite and an intro to the game. When they're ready to go, they should head off to one of the squads and get gaming.

If you feel like taking on some part of leadership, then RO is probably the most practical, unless you're very comfortable with the game and tactical flow. Check out the guide for ROs linked in the OP of this thread.
