Command An Army Units: Complete Roster with Star Costs

The complete Command An Army unit roster

Twenty-five units are currently documented, ordered by star cost. Star cost matters more than tier letter on its own, because your Star Limit caps the combined value of everything you field and a loadout built around one unaffordable 4-star unit is weaker than a squad of cheaper units that actually fit.

Rapier and Rapier Knight arrived with Update 2 on September 19, 2026. Their star costs are not published, which is why they carry a question mark rather than a guess — read the live unit panel before spending Gems on either.

Which units are worth building around?

Only four units reach S tier, and only two of those are agreed on by every dated guide.

Samurai and Lancer are the only units placed in S tier by all three dated guides checked. Flame Archer and Mace hold S in two of three. The best units by role page explains what each one is actually good at, and the unit tier list ranks all 25 with the source disagreement recorded.

How do evolution paths work?

Five paths are currently documented. The level requirement and the evolve station location come from player reports rather than official documentation, so confirm both in the live client.

The Scout Rider to Lancer chain is the most valuable in the game, because it produces an S-tier unit without banner luck. The Archer line to Flame Archer is the second best, and it finishes a star cheaper. The evolution guide covers each branch in detail, including how ascension runs alongside it.

What changed in Update 2?

Update 2 went live on September 19, 2026 and added Rapier and Rapier Knight with a new Parry trait. It also raised Spearman and Pikeman squad sizes from 24 to 28 troops, which gives the spear line more battlefield control than it had at launch.

Rapier Knight is a fast melee unit built for flanking rather than holding a frontline. Community testing recorded 205 HP, 19 damage, 20% Parry, 6 range and fast speed, but those numbers come from one testing session rather than an official stat card. The Update 2 patch page has the full change list, and the codes page lists the four 300-Gem codes that shipped with it.

Update 3, the Mongol update of October 3, 2026, pushed the roster past this table. All Things How reports the first 5-star unit (Laestrygonian), a 4-star Myrmidon, three Battle Pass units, and two new evolution endpoints — Mace to Morningstar and Pikeman to Phalangite. Their star costs are not published, so they are not in the cost table above yet; the Update 3 overview carries the reported breakdown. Read the live unit panel before spending Gems on any of them.
