The Horse Artillery is similar to the Falconet in that it has high damage, a medium-low rate of fire, low hit points, and a ranged resistance of 75%. It is designed to counter all infantry and naval units, and destroys buildings with relative ease. The Horse Artillery deals 25% more damage than the Falconet and is very fast for an artillery unit, moving faster than a Falconet or any normal Infantry, but not quite as fast as a normal cavalry unit. It costs 100 coin and 1 population more than a Falconet, and cannot be built until Industrial Age. In general, Horse Artillery is a better choice than a Falconet, as it is more cost and population effective and is faster. Trunion can aid the horse artillery well, as it makes them fast enough to flee from most cavalry units such as ranged cavalry and melee cavalry such as Hussars.
"Sometime around the sixteenth century, military planners began to see the value of using horses to maneuver light artillery to the front lines of battle. European records show that some commanders integrated their horse artillery units with infantry units and even cavalry. The mobility of horse artillery units offered military leaders increased options in dealing with fluid and rapidly changing battlefield conditions."
