These units are considered to have surrendered and this is unlikely to happen unless the units that make up the formation have suffered heavy losses, a lesson there for all potential players. Units that comprise a formation may also trade losses between one another in order to bring some units up to full strength whilst those reduced to zero are removed from play. This prohibits movement in the next movement phase. Formations that sucessfully rally have to reform in this manner. Movement follows and is based on units having a number of points that can be spent each movement phase.
All hexes are clear, costing just one movement point each.
The different terrain levels serve only to block line of sight for fire combat, not to affect movement. One assumes these are gentle slopes. Units belonging to the same formation must remain adjacent to one another. There are no zones of control so solid lines of units are required to prevent the enemy infiltrating although fire combat also helps to prevent this. To enter, however, they first suffer the ravages of enemy defensive fire.
