Commander

Commanders have strong armour and greater health than regular Troopers. They employ an ability similar to that of the Loki warframe to switch places with a player; often, a Commander will teleport the player into the middle of a group of Grineer, causing some disorientation in the process. Unlike Loki's ability, a Commander's switch teleport can work through walls and doors.

Unlike normal Grineer Lancers who usually fire in short bursts with their Grakata, the Commander usually fires more continuously, dealing more sustained damage than normal Lancers.

Tactics

 * Commanders have better hide and shoot tactics compared to the regular Lancers, often taking cover when necessary, then shooting back.  If they are in cover, prioritise other units before tageting the commander.
 * This is more likely due to the Swap Teleportation ability they have at their disposal.
 * This behavior also makes them more likely to use terminals. Due to their durability, the threat of them getting to the terminal without being dispatched is large.  If keeping doors open is a priority, then focus on Commanders.
 * Commanders seem to not have plasma grenades, and are less effecient at damaging you when you are behind cover.
 * In short range, the Commander logically refrains the use of his teleportation ability, due to the likely circumstances.
 * The Commander cannot be slowed down by Freeze mods (such as North Wind and Cryo Rounds).
 * Physics Impact Damage is not listed on this enemy's ignored damage types and therefore will have armor applied to it.
 * It is therefore recommended to use other damage types against Commanders

Tips

 * Unexpectedly, the Commanders can even warp players to intended locations. This is beneficial in cases of escaping entrenched Grineer locations or even make travel on difficult tiles easier.

Bugs

 * When killed their helmet turns from grey, to a light green.
 * Occasionally, when switch teleporting the player, the Commander will move a second or so after you are transported to them, which ends up with you teleporting directly in front of them, and them disappearing shortly after.
 * Sometimes, if the Commander is near a staircase, the player can get teleported inside the staircase with nearly no chance with escape. If you cant get him to teleport you again, there is nearly no other option as abort the mission.

Trivia

 * The text on their Helmet translates to "UBER"
