Battalion Support
Battalion Support allows you to reinforce your battalion members' attacks and defenses by adding your units to their battles. Coordinate with allies to overwhelm enemies with combined forces.
How Battalion Support Works
When a battalion member launches an attack or defends a base, you can send your units to support them:
- Join allies' attacks or defenses as reinforcements
- Support units use the Support strategy only (no attack or defense strategy selection)
- Your units arrive at wave 10, catching enemies off guard
- Coordinate with battalion members for powerful combined assaults
Types of Support
Attack Support
Reinforce a battalion member's attack on an enemy base:
- You must own bases within 4 districts of the attack target
- Your support units join the attack at wave 10
- Adds extra firepower to help secure victory
Defense Support
Reinforce a battalion member's defense against incoming attacks:
- You must own bases within 4 districts of the defended base
- Support units remain hidden from attackers until wave 10
- Surprise enemies with unexpected reinforcements
Strategic Benefits
- Surprise factor - Support units arrive mid-battle, disrupting enemy plans
- Combined strength - Overwhelm defenses through coordinated attacks
- Territorial control - Strengthen allies in contested areas
- Hidden reinforcements - Defense support remains invisible until wave 10
