From the publisher:

Memoir '44 central game mechanism is Richard Borg's now famous Command & Colors game system:

The players select from the list of available Scenarios a battle over which they'd like to test their individual command skills and savvy.

Each player then starts the game with a number of Command cards which they will use, in successive alternating turns, to activate a varying number of Units (1, 2, 3, or more depending on the card played) in different sections of the Battlefield.

A unit is composed of multiple (4 for Infantry, 3 for Armor & Tanks, 2 for Artillery & Guns) Miniature figures.

Activating a unit allows it to move and possibly battle. Simple rules taking into account various Terrain & Obstacles' effects dictates the units' moves.

Battles are rapidly resolved, using special Battle dice. When hit, a unit loses a figure. Once a unit has lost all its figures, it is eliminated from the game, giving the opposing commander a Victory medal.
