In Mount&Blade, the player will generally rely upon their war party to carry fights that they and their heroes alone would not be capable of handling. Understanding the differences between the troops they can recruit and train, and how to command them to gain their fullest benefit, is the key to success as a military commander. Except in the early game, where unit costs can be prohibitive to a player who has yet to get a grasp of how to earn a steady income, players should try to upgrade their units up to their maximum tier as soon as they possibly can.
