Evacuate

Purpose
Taking this action will abandon control of the territory, immediately demolish all buildings, and load the entire population into an existing army formation (if none are available, a new formation will be created).

This currently the only way to add Piglets and Oldpigs to formations, other than ones received in your starting tribe or exploration events.

Requirements
40 Loyalty or higher in territory

0 Resistance in territory

Cannot be under Occupied Territory status
