This will have to be changed, anything already in use by LFL/Disney won't be able to be used. The guidelines are clear:
No 501st or FISD markings or branding. Period.
Any active Legion member with a valid stormtrooper costume in the specified geographic area can join.
The Team can create a name, logo, backstory, etc. for itself (names usually contain Fire Team, though this isn't required).
A list of each Team (with their specific "Teams Name") with a current list their members will be kept in the Fire Team sub-forum on the Detachment website.
A Team must have at least 2 members to start. Ideally Teams should be no more than 16 members in size, with an average of about 8-12 members, but a Team may have as many members as you wish.
A Team member must troop at least twice per year to maintain status as a member. Two or more Team members must troop together once per year to keep the group active.
The first line would include any LFL or Disney properties.
