I'm just going to make a post here that keeps track of who is in what team, for clarity:
Team A (bottom of map)
Shelton
Spc. Crota
Sgt. Masters
Subject 16
Jayden
Ryu/Kagetora
Team B (top of map)
Cobalt Squad
Team C (left of map)
Alfred
Werner
Hans
Zachary
Shakila, Hailey, and Kiara have said they'll be in Team B or C, but didn't specify which one. Slash and Agito will be in whatever team Shakila picks. Neku and Kiara say they'll be on the same team as Hailey.
Hawkeye, Alfred, Aisha, and Dr. Landon have formed their own team to disable some other experiments on the map.
James and Neville are going to Dr. Zenarchis' office. They want Stern to go with them.
Bout halfway done, but that's what I've got for now.
