Horsemen was a term given to those who rode horses as a part of their daily life. Guards who were capable of wielding a variety of weapons and riding on horseback were a common sight through Renaissance Europe.
Horsemen were mounted on one of two varieties of horse, being either the common horse or the warhorse.
When a horseman detected an Assassin on foot, they would either charge at them with their short-ranged weapon at the ready, or they would attempt to strike the Assassin with their long-ranged weapon if they tried to flee or begin freerunning.
Horsemen often held an advantage in a fight, as they could move faster, and could use their steeds to knock over enemies on the ground. However, they were vulnerable to long-ranged weapons, and could be unseated if their horses were injured while charging. Should they be unsaddled, horsemen would either challenge their enemies on the ground, or attempt to re-mount their horse.
- A guard on foot would sometimes mount a nearby horse upon becoming hostile towards Ezio. If no free horse was available, the guard would hijack one from a passing civilian.
- Horsemen could not be killed with the Poison Blade while on horseback, and had to be unsaddled first. If shot with a poison dart however, there was a chance that the horseman would fall off.
- Horsemen could not be lured by thieves, attacked by mercenaries, or distracted by courtesans.
- Certain mounted Hermeticists shared the abilities of horsemen.
- In Colonial America, Officers and Jägers would sometimes mount horses, and use flintlock pistols to attack as well as charge the player.
