In Dungeons & Dragons the fighter is a versatile, weapons-oriented warrior class. The fighter is an adept warrior who fights using skill, strategy and tactics. Similar character classes are the paladin, ranger, barbarian and cavalier.
Fighter was one of the three classes in the original Dungeons & Dragons game, then called "fighting man" (the other two were magic-user and cleric).
In the 3rd edition of the Dungeons & Dragons game, fighters get bonus feats at every even-numbered level, giving a 20th level fighter more feats than any other character class of equivalent levels.
The class covers a huge variety of professions, from knights to bandits.
There is a class in Dungeons & Dragons called "warrior", but it is not intended for the player characters, as it is a weakened version of the fighter class. It is used for non-player characters such as town guards and the like. This is in opposition to some games – such as certain installments of the Final Fantasy series – where a "fighter" character can upgrade into a "warrior."
