Ebb & Flow: The Final Communist Offensive in Korea, 22 April-10 June 1951

From BoardGameGeek:

Ebb & Flow (e&f) covers the last period of the Korean War that was characterized by mobile operations. The game begins with the launching of what turned out to be the last of the Communist strategic-level offensives of the whole war, and ends with the final UN riposte against it. The game therefore requires both players to successfully attack and defend over the course of the game. Scale. each hex on the map equals 5 miles (8 km) from side to opposite side. each game turn represents 3.5 days (hence the date-overlaps on the Turn Track). Individual playing pieces represent corps, divisions, brigades, regiments and battalions, each containing from about 2,000 to 15,000 men and/or 50 to 400 armored fighting vehicles respectively.
