Vader's 181stI wanted to try a squad with the 181st Imperial Pilots.  The 181st will have Double/Twin attack, Gregarious, Opportunist, and Greater Mobile Attack. They should have +15 to hit for 20 damage.  I know the 181st only have 20 HP, but with GMA and Evade they should survive a little better.  Also, Vader with Opportunist and Triple attack is nice.  Let me know what you think.  Thanks
