Command An Army Units Guide — Every Type, Evolution & Star Level

Command An Army fields six unit types across four star levels, and every unit sits on a fixed evolution path. This page maps the whole system: what each type does, how the evolution lines work, and how Ascension and Mastery make a single unit stronger — the three systems that decide whether your army holds a line or breaks one.

The system is deep for a Roblox game, and it is the reason this wiki exists: tier lists only make sense once you know that the “Spartan” everyone talks about is a special unit outside the regular evolution lines, and that the Lancer creators rank so highly is the third form of the Scout Rider line.

What are the six unit types?

Every unit belongs to one of six types, and matchups matter more than raw rarity:

The practical reading: a formation of one type loses to its counter regardless of star level. Creators who cover the game consistently recommend fielding two or three types and switching the frontline depending on whether you are attacking or defending a point — defense favors shields, attack favors cavalry rushes.

Which evolution paths exist?

Evolution paths are fixed lines — each form is a straight upgrade of the one before, and the final forms are what the tier lists rank: (lines confirmed against the community wiki and Eurogamer’s evolution list; stars differ per line, so the columns are stages, not star levels)

Two notes that trip up new players:

• The Crossbowman is not part of the Archer line. It is a separate 3-star ranged unit — creators describe it as a budget Fire Archer: same role, noticeably weaker, much easier to obtain. Its own evolution is the 4-star Pavise Crossbowman, added October 17, 2026.
• The Mace is a separate 3-star unit, not an evolution of the Knight line. If you are chasing a specific 3-star, check which line it belongs to before spending Gems.

How do Ascension and Mastery make units stronger?

Two separate systems, often confused:

• Ascension combines two copies of the same unit into a stronger version. This is why duplicates are good news — keep a second copy of anything you actually field instead of selling it.
• Mastery levels a specific unit up to level 20, improving its performance through use. It costs playtime with that unit, not duplicates.

The combined effect is that a fully ascended, mastery-capped 2-star can outperform a fresh 3-star in its role — creators repeatedly make this point about the cheaper lines (Crossbowman, Pikeman) being viable when invested in, even if they lose the raw tier-list comparison.

Where do units come from?

Summons, paid for with Gems — the same currency class swaps use. Gems come from quests, milestone rewards, and codes; our codes page tracks every working code and the current set pays out roughly 7,900 Gems (October 15, 2026).

The units most players chase — Spartan, Samurai, Lancer — are the top picks in creator tier lists. See the best units tier list for the current consensus ranking and why each one sits where it does, or start with the beginner guide if you are still learning the controls.

What changed in recent updates?

The game updates fast. The newest build is the Naval update (around November 7, 2026). It added Naval Warfare, a new mode, and a parry mechanic. Creators Tuki and Chrisu say it also buffed the Spartan, Knight, Spear Vanguard and Gladiator. We haven’t confirmed exact numbers or any new unit. Before that came the Halloween update (October 31, 2026). It added two units: the Executioner (Zombie Mode drop) and the Legionary (battle pass). We have no stats for them yet, so they have no pages. Creators also rank Gladiator and Praetorian Guard in recent tier lists. Those two have no confirmed stats either. See the Halloween update guide. Before that came Update 4, the Cosmetics update (around October 10, 2026), which is mostly skins and horse armor. Before that, the Guild & Ranked update (September 2026) added guilds and ranked mode. New units ship with the bigger patches, and this page is re-checked when the game updates.

The Mongol update (early October 2026) added seven new units. It also brought the skill tree, a battle pass and a new mountain map. We have pages for the three biggest new units so far:

If you only chase one, testers rate the Laestrygonian and Myrmidon well above the Khorchin. The other four are Nökör and Bataar (battle pass 3-stars) and two new evolutions, the Morningstar and the Phalangite. The Mongol update guide has the full list.
