The formation and facing of each company in a regiment can be locked in order to give tactical advantage to the larger formation. Kohan also seamlessly incorporates advanced ideas such as zones of control, supply, population and detection. The zones add a whole new level of strategy. For example, units regenerate when in supply and automatically attack enemies that cross into their zone of detection. In addition, zones of control and detection change based on the surrounding terrain.
Buildings also have guard zones, which trigger the deployment of local militia.
Finally, terrain, fortification level, and morale are also factored into combat. Though this may sound complex, companies, regiments, zones and more are all explained in simple terms in the tutorials. The whole system works very well and becomes second nature after your first campaign scenario. The computer AI is relentless and provides a challenge even on normal difficulty level. Skirmish mode is also available, as well as a full-featured map editor.
