When you join add JSims4 (Temp) and ill invite you to a ps3 chat room that you should join when ever you feel like trying out the javelin squad. This will make it so that you dont have to add everyone that joins the platoon but you can still Contact them.
Ever seen The Javelin Squad Videos on Youtube by JurgenCutters?

That why where here so you can always find someone to do this with you when ever you want.

IF you ever want to squad up just post something on the wall about it and try to get with other members.
