From the publisher's website:
Korean Battles is an operational-level simulation of three engagements in 1950: the holding action at the Pusan Perimeter (August – September), the battle to retake Seoul (September), and the withdrawal from the area of the Chosin Reservoir (December).
The games all two-player, but are easily adaptable for solitaire. The time and space scales vary from game to game, and units of maneuver are battalions, regiments and brigades, with divisional-sized ones in some scenarios.
The components to a complete game include rules, one 34x22” mapsheet containing three sub-maps (hexagonal), and 280 die-cut half-inch (small-size) NATO-style counters.
The basic system used is a modification of the familiar "Fire and Movement" system used in Decision Games' modern era folio games.
