'Huscarles' in the Imperium means what the Imperium means by 'huscarles'. Which is not the same thing as what early medieval Scandinavians meant.

And some Heorthganete and Huscarles were used away from the lords, many Thegns wrre vassals, thegns were never huscarles, and most stereotypical "viking" elements owe more to Maestro Wagner than to History. Same with Feudalism and Sir Thos. Mallory.
The 3I concept is close enough to 6th C Scandinavian for valid comparisons.
But let's unpack a fww terms for them.
- Jarl: the noble class. Men were usually warriors.
- Thegn: a social class of high-born warriors. Equivalent to Knights or Gentry, relatively, but less aloof than later medieval gentry due to harsher conditions.
- Ceorl or Carl: social class of Freedman or freeborn, could be warriors or craftsmen. Degraded thegns might be allowed to be Ceorls, but might not.
- Heorthganete: Hearth Guards, could be house thegns, ceorls, even trusted bondsmen.
- Huscarls: literally, ceorls of the house. Freeman paid to fight for the lord, usually including lodging, food, and loot. Full time professionals, usually. Sometimes also used for skilled ceorl craftsmen on patronage, but if that's period use, I can't verify.
Keep in mind that the huscarles might be the only full time soldiers, that lords seldom sent troops without going too, and there begins the "eliteness of the huscarles. "
