In Covering Force, you are the Colonel commanding the 11 th Armored Cavalry Regiment or the commander of the Soviet 8 th Guards Army. The missions are simple. The 11 th ACR must identify the Soviet main attack so the V Corps Commander can position the Corps to destroy it. For the 8 th Guards Army: Punch a hole through the 11th and make for the Rhine.
The 11 th ACR is reinforced with 2 divisional squadrons, 3 armor battalions, and a mechanized infantry battalion, plus 9 battalions of artillery to stop a 17-motorized rifle & tank regiments.

The 11 th ACR sector is shown on 6 11x17 inch maps based on period 1:100,000 maps of the 11 th ACRs. Hexes are .75-inch hexes across and represent 1500 meters. The sector is 108 kilometers wide but only 30 to 5 kilometers in depth. You must be stubborn!

Up to 8 Scenario’s will trace the Regiments organizational evolution from 1975 (M551A1 Sheridans and M114A2 Reconnaissance Carriers) to 1990 (M1A1 Abrams and M3A1 Bradley Cavalry Fighting Vehicles) against a relentless foe.

The Fog of War drapes the field: units start showing only a blank symbol. When identified, they flip to show their identify, but unit values remain hidden.

Units are rated for command and training; you must pass a command check to move, engage, or call for support. Command Cards provide additional effects with a minimum of complexity.

Images will be coming in the not too distant future.
