There are various level 60 named Commanders and Veteran Battlemasters that spawn in specific locations on specific planets (one per faction per planet). Killing a named Commander or Veteran Battlemaster will give each member of your group a Command, Engineering, or Logistical Encryption (up to 12 per Commander/Veteran Battlemaster). Veteran Battlemasters also have a chance of dropping one Command, Engineering, or Logistical Framework, while named Commanders are guaranteed to drop one of them.

You'll need a group of around 3-4 players to kill a Veteran Battlemaster and 7-8 players to kill a named Commander.

Veteran Battlemasters have 839,340 HP and named Commanders have 5,117,842 HP. Only one will be "up" at a particular location at a given time, so you'll see one or the other, or none at all (if one was recently killed).

Named Commanders have an additional mechanic in which a 6-hour "Planetary Shield" buff on them will prevent all damage while active. To remove the shield, you must wait for the buff to run out, or you can use a Flagship: Starfighter Flyby (if your guild currently has control of the planet) to remove it immediately.

Note: The Republic Battlemaster/Commander is only killable by Empire players, and vice versa.
