The origins of Megablitz lie in Chris Kemp's NQM (Not Quite Mechanised) wargames rules, where individual playing pieces represented company-sized units.
Hidden Strength Point markers are attached to the back of each stand, and are changed by a commander when the unit loses Strength Points as a result of combat.
This means that large battles (such as Kursk) can be fought out on the tabletop in a day of real time.
The Combat Matrix reflects the fact that units suffer different levels of casualties depending upon the orders they are carrying out.
It works as follows: The main advantages of this system are that it is quick to use and it keeps the effects of combat secret from the opposition.
