The Guerrilla Tactics School, also known as the GTS, is a facility responsible for training soldiers. It provides purchasable bonuses for the entire army and a staff slot which can train rookies into a class chosen by the Commander.
A Guerrilla Tactics School is required for the player to equip PCS upgrades on their soldiers. Destroying a Guerrilla Tactics School will revoke access to any passive features purchased at the GTS.
Construction and effects[edit | edit source]
The Guerrilla Tactics School has no technology requirement and no upgrades.
| Construction | Cost | Power & Upkeep | Effect |
|---|---|---|---|
| Initial Construction |
|
|
Has a single staff slot for a rookie. When staffed, the rookie is trained into one of the four basic classes. Also allows the purchase of army-wide boosts for supplies. |
Training[edit | edit source]
The GTS is capable of training rookies into any of the four basic classes - Grenadier, Ranger, Sharpshooter, or Specialist. To train a rookie, first click on the grey staff slot below the GTS. This staff slot is visible when zoomed out in the Avenger view. Once you have chosen a class, the rookie will need to stay in the GTS for five straight days, or ten on Legend difficulty, before their training is complete.
Once training is complete, the soldier will emerge as a Squaddie of the chosen class. Their earned experience will not be changed.
While training in the GTS, the soldier may not be deployed for any missions or covert operations, and will not be deployed on Avenger Defense or Chosen Avenger Defense missions. A soldier's training can be cancelled by clicking on the white staffing icon. Cancelling their training will return them to active duty, but all training earned on their promotion will be undone.
Tactics[edit | edit source]
It is possible to spend supplies on tactics. These are passive boosts to your entire army. Many tactics have a rank requirement - at least one soldier must have reached the listed rank in order for the tactic to be purchasable. All tactics are applied instantly upon purchase. Destroying the GTS will revoke access to purchased tactics until the facility is re-constructed.
The list of tactics available for purchase is greatly reduced when playing the War of the Chosen expansion. Many of the tactics present in the vanilla GTS instead appear as resistance orders.
