Editing Ground Forces Overview (section)

=== Ground Forces Replacements ===
{{VersionChanged|1.12.0}}

Managing ground force replacements after combat can involve significant micromanagement, especially with detailed Orders of Battle.  
An automated replacement system has been added.

Each formation may be assigned a '''Replacement Template'''.  
By default, this is the template originally used to construct the formation.  
It may be changed using the '''Change Temp''' button on the Order of Battle tab.

When changing a Replacement Template, you may optionally update all formations that currently use the same template.

Replacement Templates may differ significantly from the original composition, allowing:

* Adding new capabilities  
* Removing obsolete unit types  
* Updating formations to new standards  

Each formation also has a '''replacement priority'''.  
Replacements are assigned in descending priority order.  
New formations default to priority 10.

A formation may be flagged as '''Use for Replacements'''.  
Such formations do not receive replacements; instead, their units are used to reinforce other formations at the same population during the Ground Replacement Phase (each construction phase and after ground combat).

Over time, new Ground Unit Classes will be designed.  
To manage evolving designs, units may be organized into '''Unit Series''' using a dedicated tab.

* Drag units into a series to group them.  
* Dropping onto the series name places the unit at the top.  
* Dropping onto a unit places it below that unit.  
* Dragging a unit into empty space removes it from the series.

When replacements are required, the system uses the '''Unit Series''' of each unit in the Replacement Template rather than the specific unit class.  
This avoids the need to update Replacement Templates when new versions of units are created.
