You can gather a horde of them very quickly.

Why are Khuzait Heavy Horse Archers Great:

They are equipped with a sword, a bow and two quivers of arrows.

A hundred horsemen, circling and shooting hundreds of arrows into you, an unstoppable force of nature. You watch in terror as your men form a circle, and theirs do too. You are a foot soldier in an Imperial army, and you crest the hill of a field to see a hundred of these cavalry charging at you. They are the easiest to progress to in their tier, and this allows for droves of high caliber troops to be accrued alarmingly quickly. Khuzait Heavy Horse Archers are the best non-noble horse archers in the game.

You can run a small group of these guys into a Khuzait horse archer horde and most of the time it will keep them off your footmen, possibly even killing the vermin in the process.

The arrows they use are highly armor piercing, aka good for killing horses.

They have a sword AND a shield, which makes them excellent for dealing with other cavalry and archers AHEM KHUZAITS AHEM.

They are high armor, so they can take quite a beating.

They are tier five, and getting to them is quite challenging with their troop tree progression.

They come with sword, shield and good bow and arrows.

While it is hard to get them in large numbers, if you do you can do a lot of damage to both cavalry and footmen alike. Here we see their tier 5 horse archers, and boy they can be good. The developers of this game seemed to have put a secret key into it for defeating the Khuzait, and that key is the Aserai.

They have two quivers of arrows, furthering their ability to do well in a siege.

They're better than Arboreals, more plentiful and therefore easier to stock your castles with and forget about.

They really have the same stats as most other tier five archers, except they fall a little short in equipment and armor when compared.

They are equipped with a long sabre and recurve bow.

They will still do a great job in a walled environment, but there isn't much reason to choose them over the other eight archers on this list. These guys are good for siege defense because if you're acquiring Khuzait units, it's for their horse archers and not these guys. The Marksman is perfectly average compared to its other tier 5 counterparts, and that just means it's twice as strong as it should be. Khuzait, Khuzait, Khuzait… why would you EVER have a non-noble foot archer unit that was worth being in this list while the Battanians don't? I don't know, but they do.
