Knight

The Knight (アーマーナイト Āmā naito), also known as Armor Knights or Armors, is a heavily-armored combat physical class that recurrently appear across the Fire Emblem Series. Often wielding Lances as their sole weapon of choice, Knights are generally hampered by low Movement and compensate for this with their good physical stats across the board. They are one of few classes that count as armored units, which leaves them vulnerable to bonus damage from weapons such as Armorslayers and Hammers.

Combat
Knights are considered to be bulky powerhouses, owing to their high HP and Defense allowing them to ward off the onslaughts of a variety of hostile attackers for several turns. Due to this, it is a good idea for the player to deploy their Knights on the front-lines in order to stall strong foes or protect weak allies. Movement for Knights tends to be low, so usage of boots is often recommended. The main threat to a Knight takes the form of armour-slaying weapons, as this variety of weapons can fell them fairly easily. In addition to this, it is not at all difficult for enemy units to access such weapons due to their fairly low weapon levels.

Yet another glaring weakness of Knights is their low Resistance, making them vulnerable to magic-based attacks. An exception to this is Radiant Dawn, where Armor Knights possess high Resistance for a physical class.

In Fates, the Natural Cover skill that Knights learn at Level 10 and above further amplifies their ability to withstand enemy onslaughts, as it reduces sustained damage when they are traversing terrain that hampers their movement.

Promotion
Knights promote to Generals in most games. In Gaiden, they are a second-tier class that can promote into Barons. In The Sacred Stones, Knights are one of the promotion options of Recruits and may promote into either Generals or Great Knights. In Ankoku Ryū to Hikari no Tsurugi, Knights are not able to class change, despite the General class already existing at the time.

Variations
In Genealogy of the Holy War, Thracia 776 and Radiant Dawn, there are a few Knight variations:

Lance Armor
Lance Armors (槍重装兵 Yari jūsōhei / ランスアーマー Ransu āmā, lit. Heavy-Armored Lance Soldier/Lance Armor), also known as Armored Lances, are the most common and definitive version of this class, employing Lances as weapons and appearing in every Fire Emblem game. In most games, they are simply called Knights (or Armor Knights, in the Japanese versions); only in Thracia 776 and Radiant Dawn is the name Armored Lance used. In Radiant Dawn, they are the first-tier class of the Lance Generals. As depicted in Genealogy of the Holy War and the TCG game. they are exactly the same as regular Knights.

Axe Armor
Axe Armors (斧重装兵 Ono jūsōhei / アクスアーマー Akusu āmā, lit. Heavy-Armored Axe Soldier/Axe Armor), also known as Armored Axes, are knights only able to wield axes. Dalsin, from Thracia 776, is a playable example. In Radiant Dawn, they promote into Axe Generals.

Bow Armor
Bow Armors (ボウアーマー Bou āmā, lit. Bow Armor) are only featured in the Jugdral Series. They can wield only bows, and are an enemy-only class.

Sword Armor
Sword Armors (剣重装兵 Ken jūsōhei / ソードアーマー Sōdoāmā, lit. Heavy-Armored Sword Soldier/Sword Armor) also known as Armored Swords, are sword-wielding knights. Playable examples are Arden and Meg. In Radiant Dawn, they promote into Sword Generals.
