I am planning an EarthForce Campaign that starts at 1st level in 2246. They will be part of the Tunnel War and get trapped for the rest of the war. They will be around 3rd level in 2248 and advance one level every other year after that as members of a ships crew rising to command, that will make them about eigth level at the start of the series (with one of the characters in command of their EF ship), then they will have to decide what to do about Clark...do they join Sheridan? do they join the Rangers? do they remain 'loyal' to EarthGov and clark? could get interesting...
