When this option is chosen, the Entrench per Unitgroup box will appear. Once a landscape type is chosen within this box, two buttons will appear.
This box shows two variables. AutoEntr, which is an automatic entrenchment variable that determines the maximum number of entrenchment points a unit within this landscape type can gain each turn. This number is a maximum, the actual number of entrenchment points a unit will be limited by a unit's entrench power, which is assigned for each subformation type using the EntrenchPower button in the Statistics 1 option of the property sheet box in the SFT window .
Once a landscape type is selected in the Entrench per Unitgroup box, two buttons become available to modify the selected landscape type.
AutoEntrench. This button will assign a number to AutoEntrench, which determines the maximum number of entrenchment points a unit can gain per turn if it has sufficient entrench power.
MaxEntrench. This button will assign a number to MaxEntrench, which determines the maximum entrenchment points a unit can have in the selected landscape type.
