Module Information

ITACS or Improved Tactical System is a hex-and- counter wargaming system which simulates tactical battles from the earliest times until the end of the 16th Century. It is designed to include some of the flexibility of miniatures style games along with the ease of use and faster gameplay of the hex based wargaming world.

ITACS has been inspired by various tactical warfare games covering the period from ancient to early modern times.

ITACS contains a number of rules including the basic movement and combat rules, terrain effects, leadership, morale, etc. There are also scenarios for ITACS, each of which may contain scenario specific rules that apply only to that scenario.

ITACS is designed to be played online using the VASSAL game system, although players may choose to print out copies of the counters and maps should they so choose, and play face to face.

Game pieces and maps from other tactical games can also be used to play ITACS. You may also create your own counters and maps as well as any number of scenarios to use these maps.

Version History


Initial release


Completed the rules and added a lot more scenarios. To avoid bloat in the module file I have split the module into 3 separate modules covering Ancients (including Greece and Rome), Medieval (Europe from the end of the Western Empire in 476 through to 1600) and Asia.


A few minor rules and combat chart tweaks. Added more scenarios.
