D-Day: America Invades by Avalon Hill allows players to re-enact one of 7 battles with themselves as commanding officer. Players must engage and battle the enemy while avoiding ambushes and keeping their lines of supply open.
An extremely realistic combat sim, the game expects you to keep track of a variety of statistics that effect combat between your soldiers and the enemy, including fatigue, the commanding officer, unit integrity and morale, the unit's experience and position and a wide number of variants, among others.
D-Day: America Invades is the third in a series of games covering World War II called "World at War". ~ Lisa Karen Savignano, All Game Guide
