How to Get Imperial Wall in Command An Army: The Shieldman Evolution Chain

The Short Answer: Evolve a Shieldman

Imperial Wall is not a banner pull. It is the endpoint of the Shieldman evolution chain — the defensive line of the five documented paths:

Two station visits and two level-20 thresholds turn the cheapest shield starter into the best purely defensive unit in the game. The evolution guide documents all five chains; this page is the shield branch.

The Chain, Step by Step

1. Hold a Shieldman (1★). C-tier in base form, kept for its shieldwall cover and this chain.
2. Level it to 20 (the evolve threshold per player reports) and evolve at an evolve station → Sentinel (2★). Sentinel adds solid HP and shield coverage while staying cheap.
3. Level Sentinel to 20 and evolve again → Imperial Wall (3★, A tier).
4. Ascend in parallel. Duplicates feed ascension — two copies per level up to Ascension 3 — permanently strengthening the copy you keep while the evolutions run.

The beginner guide covers the leveling loop behind step 2, and the formation planning guide is where the finished anchor gets tested inside a squad.

What Imperial Wall Is Worth at the End

On a Hold formation, Imperial Wall is the best purely defensive unit in the game. It anchors a position, absorbs pressure, and buys time nothing else at 3 stars can buy. The trade-off is just as real: its offensive output is near zero, which means it stalls fights rather than winning them. Backline damage dealers do the actual work behind it.

That shapes the squad you build around it:

Treat the chain as the foundation of a squad rather than the squad itself — the current meta slightly punishes pure shield stacking because of how many block-damage units are in active play, so the wall needs damage behind it, not more shields beside it.
