How to Get Gems in Command An Army: Codes, Matches, and Spending

Every player asks the currency question first, and the honest answer has two halves: a head start you claim in minutes (codes), and a renewable income you earn forever (matches). This page is the verified record of both — plus the spending order that separates an army from a museum.

How many free Gems can you get from codes?

3,900 across six working codes as of September 15, 2026 — every one first-party, announced by the developer in the official Discord:

Roblox codes can die without notice — four launch-window codes (BUGFIX, LEBALANCE, CONQUEST, D0ggy103) already expired after Update 1. The codes page carries the tested list, the expired record, and the how-to-redeem steps; it is re-checked after every game update.

How much do matches pay?

The renewable half, and it has moved twice on the record: the September 6 patch multiplied Gem earnings per match by 1.5× — part of the biggest economy patch of launch week, alongside capture speed running 10% faster per attacking player — and UPDATE 2 cut gem earnings by 30% on September 19, 2026, then reverted all Troop Mastery and Gem reductions the same day (patch history). The multiplier is the standing rate. Two implications worth building habits around:

• Attack pays. The capture-speed bonus scales with attacking players — the aggressive side converts matches into income faster.
• Every match funds the project. Duplicates from pulls and Gems from matches both concentrate under the four-slot cap (upgrading guide).

The exact per-match Gem numbers are not published by the developer — this page records the verified multiplier, not invented figures.

What do Gems actually buy?

Three documented uses:

1. The unit summon pool — the main sink, and the only randomized one. The official 4★ rate is 0.5% (1% with Luck, 1.5% with Super Luck) — the summon odds page translates what that means in real pulls.
2. Leader class changes — changing your own leader class costs Gems.
3. Recruiting and upgrading troops — filling and feeding your four slots.

What order should you spend in?

The army building answer, in sequence:

1. The missing role first. Holder, breaker, skirmisher, flex — buy the empty role, common welcome. A coherent four beats a pile of unfed rares every time (rarity guide).
2. Documented chains carry a planning premium. Units on official evolution paths — the Mercenary line, the Update 1 arrivals — compound through Mastery and Ascension; dead-end pulls stall.
3. Rarity last. The 4★ rate makes rare pulls a tiebreaker, not a plan (summon odds).

The beginner guide sequences exactly this: redeem codes, buy roles, pour duplicates into the core four.

What is still unverified?

Per-match Gem amounts (the developer publishes multipliers, not base numbers). One question closed September 19, 2026: UPDATE 2’s 30% cut was reverted the same day, so the multiplier-vs-base question it would have raised is moot. Earnings have moved twice on record (×1.5 on September 6; the September 19 −30% cut, reverted the same day); each move lands here with a date as it verifies. One item closed September 17, 2026: the store sells no Robux-to-Gems product at any price — the game pass page carries the full first-party capture.
