On Military Matters released the Tactica II rules:
Tactica II After 30 years of global play, Tactica receives an updated, upgraded version – Tactica II – that keeps the same streamlined system using multi-based units, clarifies the existing rules, and incorporates improvements to all aspects of this game. Tactical formations represent ancient armies with movement and command control intertwined within the course of a battle. Unit fighting value still forms the core of the d6 combat system, and all significant troop types, weapons, and special tactical conditions are included to differentiate armies. Tactica II comes wirebound in 8.5 x 11 format and packed with well-playtested rules, plentiful diagrams, and army lists. Scales are approximately as follows – one figure equals 40 to 60 soldiers depending upon troop type, density, tactical operating area, and unit size; one inch is approximately 10 to 15 yards; and one turn equals about 20 minutes.Link: On Military Matters
