Charge attack

"Charge attacks" represent a special ability for some melee units that can attack while moving — that is, they can deal damage to enemy units that come in close proximity to them whenever they are moving. 
In Alexander and the Kings & Conquerors series, only Spartan units, as well as heavy chariots and Sarmatian lance cavalry would have this ability. However, in Swords of the Prophets, the number of units that can "charge" enemy units is drastically increased, with the Norse and Tibetans having the lion's share of units capable of doing such attacks.
