The Soldiers are the most basic class, and most common, type of enemy you will find. They fight using their muskets or move in for fisticuffs or swordplay. If in prolonged combat, there is a chance some of them will form up a Firing Line. That is the sole risk they pose ... and numbers.
With no special training they are easily the most vulnerable type of enemy. Take your pick of lethal weapons. You can kill them with it without much effort at all.
