=== Ground Unit Training Costs by Population ===
{{VersionChanged|2.6.0}}

Training costs for formations with special capabilities may be reduced depending on the environment of the training population.

If a Ground Unit Class has capabilities such as:

* Desert Warfare  
* High Gravity  
* Extreme Temperature  
* etc.

…those capability multipliers are **free** if the formation is trained on a world where those conditions naturally occur.

Example:  
A Desert Raider infantry unit costs 0.375 BP each.  
A 2000‑unit formation costs 750 BP.

Training on:

* Desert world → 600 BP (750 / 1.25)  
* Desert world with extreme temperature → 400 BP  

Cost is locked in when training begins (not when queued).

The normal cost is shown on the Ground Forces window.  
Any reduced cost is shown on the GU Training tab.

Free capability environments:

* High Gravity — gravity > species maximum  
* Low Gravity — gravity < species minimum  
* Extreme Pressure — pressure > species maximum  
* Extreme Temperature — temperature outside species range  
* Mountain Warfare — terrain includes “Mountain” or “Alpine”  
* Desert Warfare — terrain includes “Desert” or “Arid”  
* Jungle Warfare — terrain includes “Jungle” or “Rainforest”  
* Rift Valley Warfare — terrain includes “Rift Valley”
