Korea: The Forgotten War v5.0 - part of the Operational Combat Series - contains the counter and map changes for the 2nd edition of Korea.
It also includes a number of right-click menu/shortcut key options to add appropriate markers (DG, low supply, step losses, etc.) and to mark mech units as Fueled and air units as Inactive. Menu options are also available to clear DG and Trainbusting counters by side and to reset Fueled markers.
