Units can now reinforce other units of the same type that are damaged, combining the health, supplies, and ammo of both Units involved. Units now may be removed from the board, meaning that they do not occupy any Tile (e.g. when a Unit is loaded into a transport). Units who move onto a friendly Unit are removed from the game board after moving into the destination Tile, allowing Units to perform some action (such as Reinforce or Load) after moving onto another Unit.
