Overall, this process is smooth and intuitive once it is learned. If it falls within your appropriate range you are allowed one action. If it falls within the opponent's range, he may perform one action. If the dieroll is a modified '7' a random event may occur. Units which perform actions beyond the second action may begin to attrite.
Attrition manifests itself in the form of disruption or step losses - or eventually elimination.
Clearly, this continuous movement system allows virtually unlimited flexibility with units vis a vis fighting and moving, but can eventually become costly in terms of attrition. It is not always easy, but it can be done. This leads to the subject of command. While in command the group may perform actions as a whole. Just as important as coordination in movement is coordination in attacking.
