"Lima Force" is the code name for Lima Fleet's special tactical unit. Little has been published about Lima Force's structure, members, or missions, although it is known that Lima Force answers directly to Commander in Cheif, Lima Fleet.
What IS known is that Lima Force personnel wear black uniforms aboard their own commands, and when in the presence of non-Lima Force personnel wear standard uniforms.
Lima Force is one of two covert units within the fleet. The other is the Special Intelligence Unit. The primary difference between Lima Force and SIU is that Lima Force takes direct tactical actions against enemy forces, including the use of Starfighters and major fleet units, while SIU is primarily for covert intelligence gathering. Their missions do have some overlap, as both units employ highly skilled snipers for certain missions.
