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.'"

Commissar is a unique Automaton unit that appears to be in the leader position of Automaton infantry squads.

Tactics

 * The Commissar is a unique bot responsible for calling in bot drops as a first action. (Other infantry are also capable of calling in bot drops). Helldivers are advised to keep their eyes sharp and gun down the Commissars before they can launch their signal flares, especially on higher difficulty missions where Bot Drops can easily bring in sufficient number of heavily armed socialists to overwhelm the team.
 * Commissars can toss grenades at Helldivers, these grenades can be picked up and thrown back at the enemies by daring Helldivers.
 * At higher difficulties, Commissars gain a “surprise” secondary ranged attack that deals significant damage and ignites the player. This attack involves the Commissar charging its pistol’s flare and then firing the flare at a Helldiver rather than using it to call in a drop ship.
 * 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, while avoiding getting close to it, is to aim for headshots or use grenades for a quick takedown.
 * If a Commissar leading a patrol finds evidence of Helldiver activity it will usually sprint into the area to investigate while the other Automaton slowly lag behind. Helldivers can use this to their advantage to single out and eliminate the Commissars before dealing with the rest of the patrol.
