SCAVs can be player controlled or non-player controlled entities within Escape From Tarkov lore who "gather into packs, living by dog-eat-dog rules, cutting each other's throats over a better piece.". They are constantly roaming and defending certain areas on every map and are commonly recognized by voice lines. They carry generally bad gear and low tier armor and aren't normally a large threat to players.

Raiders are people within Escape From Tarkov lore who are "A shady group of armed people who, according to rumors, consist of former PMC operators and local residents. They possess great combat and tactical skills". Raiders are more difficult to take down and usually carry decent weapons.

Raiders have a health pool of 750 HP. Their weapon presets consist of shotguns, AKs, pistols, M4s, SMGs, and PDWs. Raiders weapons are almost always modified and their magazines contain mid grade ammunition. When fighting Raiders, remember they are exponentially more accurate than normal SCAVs. A Raider will often "Head, Eyes" you from a distance and without warning.

Rogues are a faction of ex-USEC PMC operatives. Rogues are debatably the hardest AI to kill in Escape From Tarkov.

Rogues only spawn on the map Lighthouse, and have a health pool of 770 HP. They can carry pretty much any weapon, but tend to utilize assault rifles. A Rogue's weapon is always modified and their magazines contain mid to high grade ammunition. When fighting Rogues, remember they are dead accurate and can 1-tap you from long distances, and even through some walls. Rogues will shoot BEAR PMC operatives on sight, but will allow USEC operatives up to 50m of their group. Once you shoot a Rogue, you will become hostile to all Rogues in the compound.

Cultists lurk in the shadows in groups of 3-5, waiting for a player to approach. They silently approach their enemies and stab them using either normal knives or, in case of the priests, the poisoned Cultist knife. If fired upon, the Cultists will return fire using firearms and grenades. After they attack a player with their knife, they may choose to run off into the woods again and attempt to attack the player(s) from the shadows once again. Some Cultists have been seen to prone in the grass or hide in bushes while their companions engage the player(s) with weapons, then attack with their knives when it's least expected.

If stabbed by the Cultist knife, players will be inflicted by the Unknown toxin debuff, which deals gradual damage over time and causes pain. The toxin can be cured by the xTG-12 antidote injector or Augmentin antibiotic pills otherwise, the player must extract from the raid or they will run out of medication and die.
