The counters represent regiments and batteries. The map is scaled at 1000 feet per hex with Centreville in the northeast, Sudley Mountain in the northwest, and Manassas at the south edge. The color scheme is chiefly white clear terrain, green woods, and yellow hilltops. The time scale is 45 minutes per turn and the game lasts up to 20 turns.
Movement tends to be slow.
Also, there are limits on how many units can move into enemy ZOC's per brigade and per side in a single turn. Otherwise movement is limited to a single hex. Out of command units roll individually and receive a full move only on a 5 or 6. Command is ultimately derived from the army commander. The CSA has no division commanders but the presence of two army commanders allows some flexibility.
