Armor Heavy Team is an official updating and expansion of the TacForce rules published by GDW/GHQ and done with the permission of GHQ.
They cover tactical combat from 1950 to 2015.
It is the most detailed set of rules ever written for the open market while still remaining playable.
They are broken down into three levels depending on the amount of detail the GM and players wish.
The rules include sections for
Urban Combat,
Combat Engineering,
Command Control and Communication,
Maintenance,
Night Operations,
Nuclear,
Biological and Chemical
and about every other kind of warfare that we have seen or will see.
While the base game only comes with the classic cold war era vehicles, additional vehicle sets are available.
