Combat is a common practice in Mount and Blade II: Bannerlords. A majority of the time, you and your army will start a campaign with a horse available to you, making it significantly easier to travel between destinations. During combat, you may want to fight on a horse, but if you also may want to change your strategy and attempt to dismount, fighting your enemies using your two feet.
You have a chance to choose if you want to mount or dismount your horse during combat. All you need to do is look down at your horse and hold the “F” button to get off of it. You can also choose to hit the “Z” button to dismount it, but will need to hit the “F” key if you want to get back on your horse. You won’t have to option to return to your horse or get off of it during combat when enemies are nearby. You don’t want to attempt to dismount your horse during combat because you will have to come to a full stop to make it happen. You’re better off making the decision early before troops are rushing after you.
All commanders have the option to make the same decision with their army. If you want your troops to get off of their horse, you need to hit the F5 key. They will dismount, and they will stand near their horses, ready for combat, and continue awaiting your orders. When you want to remount their horses, all you have to do is hit the F5 key again, and they will return to riding their mounts.
It’s essential to choose the best time for your troops, and yourself, to fight on a horse. If your opponents also combatants riding into combat, chances are you want to remain on your horse to level the playing field. The same goes for if they have no mounted fighters, giving you a clear advantage during the battle. The choice is yours, and the weapons available to you and your army may determine what is a better choice, along with the skills or perks you have.
