specialist?

[Bobochen]

Never really thought about this but are all 'non normal creeps' specialist? including boss?

[Richard Cranium]

Specialists will disable you in some way
Elites are mobs+
Bosses are classified as monstrosity

[herrschneider]

This is just guesswork, but I assume that every enemy with a specialized weapon (maulers, ragers, flamers, snipers, bombers, ogryns and the walking bombs) count as specialists. If they also count as "Elites" I have no idea. Might be that Elites are hardier versions of those specialists, but it might just be a synonym for specialists. Still, only my guess, I have no idea.

No. Specialist are all enemies that have "non-regular" attacks, such as trappers, mutants, flamers, bombers.
Gunners, maulers, crushers, bulwarks are elites.
Bosses are bosses. If you are asking about armor class, then I suggest checking out this thread: https://www.reddit.com/r/DarkTide/comments/z2pn4t/enemy_breed_armour_types_and_locational_damage/

makes sense, I'll accept that as fact

[Doxorn]

Bosses are monstosities

Mauler, Gunner, Shotgunner, Ogryns, Berserkers are elites

Sniper, Pox Burster, Flamer, Pox Hound, Trapper, Mutant, Bomber are specialists

If you go to the Psykanium all the specialists are bundled together. Everything else you can mark there is elite.
Ogryns and bosses also count as unyielding.

Bottom line:
Anything that is not boss or specialist but can be marked are elites.

Elites are mobs that function like basic mobs but are beefed up, your maulers, crushers, ragers, gunners fall here.

Specialists are mobs that don't act like basic mobs. Flamers, bombers, netters, snipers fall here.

Monstrosities can be summed as 'anything with a hp bar at the top of the screen'

Elites can be found standing around before getting Aggro

Special spawn with a sound cue (normally) and can't be found just standing around with other enemies
