Rate of Fire, or R.O.F., determines the rate of attack that a unit have. The R.O.F. of a unit is a measurement of time between the attacks that it makes (A unit with an ROF of 3 fires, or can fire, a shot every 3 seconds). Most ranged units, such as Musketeers have a ROF of 3. All ranged cavalry with bows, such as the Bow Rider and Cavalry Archer have an ROF of 1.5. All melee attacks have an ROF of 1.5, and cannons ROF are normally in the ballpark of 5-7, but not always. The Chinese Flamethrower is a very special case, having an ROF of 0.5.
