Command an Army is a medieval strategy game on Roblox where you recruit units, hold the line against enemy waves, and capture points to dominate the battlefield. Summoning strong units costs Gems, and grinding for them takes time. The fastest shortcut is redeeming active codes, which drop free Gems and Skill Crystals directly into your inventory so you can focus on building your roster instead of farming currency.
All working Command an Army codes (October 2026)
These codes are confirmed active as of October 12, 2026. Redeem them before they expire since the developers can deactivate codes without warning.
| Code | Reward |
|---|---|
| COSMETIC | 2,500 Gems + 10 Skill Crystals (newest) |
| MONGOLS | 1,000 Gems + 2 Skill Crystals |
| OCTOBER3 | 1,000 Gems |
| SATURDAY | 1,000 Gems |
| LAESTRYGONIAN | 700 Gems + 2 Skill Crystals |
| UPDATE3 | 700 Gems + 2 Skill Crystals |
| SKILLTREE | 5 Skill Crystals |
Redeeming all seven active codes nets you roughly 6,900 Gems and 21 Skill Crystals combined. That is a meaningful head start on summons, especially early in a new save.
How to redeem Command an Army codes
You cannot access the code menu until you finish the opening tutorial. Once that's done, the process takes about 30 seconds:
- Launch Command an Army on Roblox.
- Find the Codes button on the right side of the screen.
- Type one of the active codes exactly as shown above.
- Press Claim to receive your Gems.

Why aren't my Command an Army codes working?
A few things can break code redemption. Check these before assuming a code is dead:
- Typos: Enter codes exactly as listed. One wrong character kills the whole thing.
- Case sensitivity: Command an Army codes are case-sensitive. SHIELDBREAKER and shieldbreaker are not the same input.
- Expired codes: Developers pull codes without warning. If a code fails and your spelling is correct, it has likely expired.
- Tutorial not completed: The redemption system is locked until you clear the opening tutorial.
If everything looks right and the code still refuses to work, leave the game entirely and rejoin before trying again.
How to find new Command an Army codes
New codes tend to drop around updates, balance patches, milestone events, and bug fix releases. The official COMMAND AN ARMY Discord server is the fastest place to catch announcements directly from the development team.
For other Roblox games running active code promotions, the Roblox guides collection covers a wide range of titles. If you play tower defense games alongside Command an Army, the Toy Defense codes guide and the All Star Tower Defense X codes guide both have free currency lists worth bookmarking.
What are Gems used for in Command an Army?
Gems are the primary resource in Command an Army. They go toward recruiting units and expanding your force. Starting with a healthy Gem balance from codes means you can skip the early grind and get to the more interesting strategic decisions faster. The difference between a strong opening roster and a weak one comes down almost entirely to how many Gems you can put to work in the first few sessions.
For players who enjoy collecting free currency across multiple Roblox titles, the Arsenal codes guide is another solid stop for free skins and in-game currency.
