Unlock Requirements and Why This Branch Matters
Army Building only appears once Peace Shield is fully complete, which already makes it a late-game branch by definition.
- Unlock requirement: 100% Peace Shield.
- This branch is a true follow-up, not an alternative early path.
- The biggest cost walls arrive well after the opening nodes.
That is why Army Building is usually planned as part of a late combat roadmap rather than a broad early recommendation.

Opening structure cleared — 29,230 badges
The first eight nodes are still relatively controlled and mostly serve as setup before the real branch cost begins.
Mid combat block finished — 172,030 badges
After the two three-node combat clusters, Army Building has already become a major badge commitment.
Second major wall — 463,690 badges
The repeated 15-level branches are where Army Building starts to feel like a true late-game cost wall.
Full branch — 627,130 badges
The late Fire Up, Armor Upgrade, and final Recharge Shield turn Army Building into one of the site's larger research commitments.
How to Use Army Building in Your Research Plan
Army Building is less about early efficiency and more about whether your account is already ready for a serious late-game badge branch. It only makes sense after Peace Shield is fully done and your earlier value branches are already locked in.
If you are still comparing whether to push Army Building or something even deeper, use the Unit Special Training Costs page to compare the next major badge wall.
