Commissar

A crude simulation of military leadership, the Commissar is augmented with slightly faster processing and a crude command subroutine. The Commissar stays out of combat if possible, as despicably cowardly as it is unequivocally non-sentient.

Tactics

 * They perform a combo of melee and ranged attacks, but they'll only start to come after Helldivers once the Troopers, Raiders, and Marauders have been cleared out.
 * The Commissar is vulnerable to grenades and headshots. The best way to defeat it by avoid getting close to it, aim for headshots, or use grenades for a quick takedown.
