How to unlock the Ringleader achievement in Section 8 - Definitive Guide
Start up the match and deploy, then get somewhere safe after burning in. Once you're safe press the back button and tab over to the dropship menu. That done, go down to squad select and join a new squad. Then select your squad (squad management) and invite players. Invite the AI players. Repeat a couple of times and you've got the achievement.
It's important that you have no other humans in the game, or at least on your team, if there are then you can only invite them to your squad when you hit "Invite Player" at the squad management screen.
This can be done in private or ranked matches. Each team (section 8 or arm of orion) has 6 squads (Alpha, beta, gamma, etc) You can join any squad under 'squad management' from the dropship menu in game. Next, make sure one of your friends is on your team and invite the to your squad by clicking on your squad twice, then click Invite friend and select your friend from the list. You can kick the player and re-invite them 10 times until the achievement unlocks. If you don't have anyone to invite, you can also do this with bots, but only in instant action.
Start a private match with bots (non swarm is best). Press on the D-pad before you burn in, then to cycle through pages to the one with squads. Kick the bots in your squad, then re-invite any of them. Do this a total of 10 times for the trophy.
