What each level can do
Applies to every program unless a program override says otherwise. Changes save as you tick and reach phones on their next refresh.
TL rights apply to the Team Leader's own team only. Everyone always sees their own team, housing, gear and damage reports. Depot (Hawk) always has full access; that can't be switched off here.
Which job titles count as which level
Comes from the job titles programs arrive with. New titles get sorted on Depot's program approval screen, and land here once they are.
Team Leader isn't a job title. An SKL assigns it inside Program C2, per team, and it adds the TL column's rights on top of the person's own level for their team.
