As of 1.06, you'll have to distinguish between progressive era battles and battles in previous ages. Having gathered some info about this new battle system, I thought it'd be a good idea to write a small explanation for all. Please find it below.

Progressive era battles
Progressive era battles are battles in which there is at least one unit from the progressive era in the attacking or defending army. They can be easily recognized by their new lay-out with trenches and craters, see attachment.

Progressive era battles will use a scaling factor for range and movement. This means that every hex on the battle field will no longer be counted as 1 hex but more. How much more is directly related to the used scaling factor. The current scaling factor is 1.5 - possibly subject to change by game design. Such a scaling factor is used because the range and movement of units is becoming increasingly larger. As we have to respect a certain minimum resolution, it is impossible to enlarge the battle field proportionally (i.e. add more visible hexes). To solve this problem, a scaling factor is used.

The implementation for range and movement is a bit different. We'll discuss both separately.

Note! The scaling of the values logically affects all units in a progressive era battle - also non-PE units.

Range
The range values displayed in the army management are the raw data (that can be compared to other units), the range values on the battle field have the scaling factor already taken into account.

With a scaling factor of 1.5, a unit that has a range of 8 hexes in the army management will be able to fire for 6 hexes (*) during progressive era battles. Every visible hex will thus count for 1.5 hexes. The range that you'll see when hovering over that unit in the battle field will be displayed as 6.

(*) 8 / 1.5 = 5.3333 = 6. The system automatically rounds up - never down.

Movement
How far a unit can move on the battle field is dependent on 2 variables:
- Its movement points, displayed when hovering over the unit.

- The movement costs of the battle surface. Each hex on the battle field has a movement cost depending on its surface. E.g., plains have a movement cost of 2. A bush tile has a movement cost that is higher than that of a plain, and the movement cost of a swamp is higher than that of a bush. (FYI - Depending on the total movement cost of the surface, it is thus possible that a unit that is placed on a different location cannot move as far as an identical unit placed elsewhere.)

With the scaling in progressive era battles, the movement points of units is not changed, but the movement costs for the terrain hexes is. Subsequently, due to its implementation, the scaling of movement is not directly visible for players.

With a scaling factor of 1.5, a terrain hex that has a movement cost of 2 will be scaled to 3 (*) during progressive era battles. A unit moving over it will thus be able to move less far.

(*) 2 * 1.5 = 3


Battles in previous ages
Battles in previous ages are battles in which there is no unit from the progressive era in the attacking or defending army.

These battles will remain the same - they do not change with game version 1.06. More specifically, they still use a scaling factor 1.

With a scaling factor of 1, a unit that has a range of 8 hexes in the army management, will be able to fire for 8 hexes during these battles. The range that you'll see when hovering over that unit in the battle field will be displayed as 8.

With a scaling factor of 1, a terrain hex that has a movement cost of 2 will remain 2 during these battles.

General note! The terms "Progressive era battle" and "Battle in previous age" are non-official terms used to facilitate the explanation of the scaling factor. They do not determine (or in any way affect) in which PVP-tournament the earned battle points will be added. The already existing system for that is still valid.
