Command An Army Mongol Update (Update 3) — 7 New Units and Skill Tree

The Mongol update is Command An Army’s Update 3, and it landed around October 3, 2026. It added seven units, a Mongol battle pass, and three new features: the skill tree, Auto Delete and AFK servers.

If you only want the short version: chase the Laestrygonian and the Myrmidon. Skip grinding the battle pass just for the Khorchin.

What are the 7 new units?

Five are brand-new units and two are new evolutions of units you may already own. Stars are from the update notes on the community wiki.

The takeaway: the two new summon-tier units are the big upgrades. The battle pass is mostly a side project.

The first 5-star unit

The Laestrygonian is the headline. It’s the first 5-star in the game, so it costs more of your star limit than anything else. (Your star limit is the cap on the total stars your army can field.)

You only get nine giants per squad. Each swing hits the main target and splashes onto nearby enemies, which breaks shields fast. Sent in alone, though, the squad gets swarmed and dies. Read the star limit guide before you build around it.

The Mongol battle pass

The battle pass holds three units: Nökör, Bataar and Khorchin. The Khorchin is the 4-star reward and the only one we have test numbers for.

Our honest take: the Khorchin isn’t strong enough to make the pass a must. Fire Archers outrange it, and testers say it has very low damage and HP. If you play every day anyway, take the units. If you’re short on time, put it into your main army instead.

New evolutions: Morningstar and Phalangite

Two older units got a new top form:

• Mace → Morningstar (4★). The Mace used to be a standalone 3-star with no evolution. Now it has one.
• Pikeman → Phalangite (4★). The spear line used to stop at the Pikeman. It now goes one step further.

Evolving raises a unit’s star cost, so check your lineup first. The evolution guide has every line in one table.

Skill tree, Auto Delete and AFK servers

The skill tree is the biggest new system. It uses Skill Crystals, a new currency. Several codes from this update hand them out, including SKILLTREE, so check all working codes before you spend anything.

Auto Delete and AFK servers are also listed in the update notes. We haven’t confirmed exactly how each one works yet, so we won’t guess here.

What came after the Mongol update?

Update 4, the Cosmetics update, followed around October 10, 2026. Creators who covered it agree it’s mostly cosmetic: new skins and horse armor. One creator also reports horse leveling, a big Javeliner buff and a Spear Vanguard nerf. We haven’t seen exact numbers from a second source, so treat those as unconfirmed for now.

October 17 — the class expansion. The bigger of the two follow-ups. Two new player classes and a new 4-star unit:

Also in that patch: Skyview (press M or the map icon), an upgraded ping wheel (attack / hold / capture / move), double gems from matches, cheaper skill trees, more troop mastery XP, and smarter AI balancing — AI now fills slots by team strength rather than player count, and can fill with 1–4 star melee.

October 19 — the balance pass. Two changes that moved the meta:

• Berserker buff: unit count 16 → 18, attack damage 29 → 33 (DPS 44). It is now the highest-DPS of the 4-star melee picks, still squishy. See the Berserker page.
• Phalangite nerf: block durability 45 → 30, about a 33% cut. The spear wall still wins trades, but it no longer holds a point alone. See the Phalangite page.

October 22 — build update. The Roblox page title changed to [UPD], the first sign of a new build, and the game metadata updated that morning. We have not confirmed what changed in this build: the group shout is empty, there are no patch notes on the store page, and no creator has published a breakdown yet. We will not guess at new units or nerfs — when a creator or the group posts specifics, this page and the affected unit pages get updated.

Next: the Halloween update is live. It went up on Saturday, October 31. It adds a PvE Zombie Mode with waves, bosses and a gate to defend. See the Halloween update page for how it plays and which units to bring.

For where every unit stands today, see the best units tier list. If you missed the patch before this one, Update 2 covers Ranked, Guilds, Rapier and Reaper.
