Hello,
Specifically, the reinforcements from the left column of the platoon management screen? After the first turn, they may be swapped with existing units? What is this abstraction?
It was my mistake calling it reserves in the initial posting.
regards,
The game's map space is limited. While historically there could be more than an infantry battalion (more than 12 platoons) on the game's map square, the game allows to have maximum 4 per a square. So, it is the tool which makes it possible to have a proper number of units in a campaign but with out gridlocks on the map.
