Maykr drone

The Maykr drone is an enemy introduced in Doom Eternal. The lowest-ranked known form of Maykr, they are mostly found within Urdak but also appear in the Slayer Gate challenge found in the Mars Core level. They fire sustained volleys of Argent projectiles, and feature a massive drop of ammo if killed with a headshot.

Tactical analysis
Maykr drones normally keep their distance from the player and fire volleys of weak energy blasts; up close, they release whips of light from under their shoulders and spin on the spot to push the player away. Their bodies are covered in armor that makes them fairly resistant to damage, but their heads are highly vulnerable - killing them with a headshot will release a shower of health and ammunition. The combat shotgun's Sticky Bombs and the heavy cannon's Precision Bolt are especially effective, but any weapon can yield bonus ammo as long as the fatal shot is to the head. Maykr drones are capable of dashing to the side in between volleys to evade incoming fire.

While Maykr drones often respawn during combat like fodder demons, they are actually classed as a heavy demon so three units of chainsaw fuel are required to use that weapon against them.

Lore
Drones make up the majority of Urdak's population; like most other Maykrs, they have individual identities but are biologically unable to defy an order from the Khan Maykr. As a result, they give the impression of functioning as a perfectly synchronized colony. Their bodies, referred to as being immature, are not yet able to handle the strain of inter-dimensional travel, so they never leave Urdak.
