Command an Army: How to Get Gems Fast (2026 Guide)

If you're trying to figure out how to get gems in Command an Army, you're in the right place. Gems are the lifeblood of this Roblox medieval strategy game — they fuel unit summons, duplicate pulls for ascension, and unlocking extra classes for your commander. Without a steady gem income, your army stalls out fast.

The good news is that you don't need to spend Robux to build a strong roster. Between redeemable codes, daily and weekly quests, and smart battle farming, free-to-play players can bank hundreds of gems per session. This guide breaks down every reliable method, ranked by how much time and effort each one demands.

Why Gems Matter in Command an Army

Before diving into farming routes, it helps to understand what you're actually grinding for. Gems serve three core purposes:

• Unit summons — the gacha banner is your main source of new troops, and every pull costs gems.
• Ascension — to max out a unit at Ascension 3, you need eight copies of the same four-star unit. That's a massive number of pulls, which means a massive number of gems.
• Class unlocks — the tutorial gives you one free class. If you pick Sword and Shield, for example, options like Assassin and Hammer stay locked until you buy them from the classes menu.

In short, gems convert directly into army power. Community reports consistently show that players who farm efficiently can pull several times per week without spending a cent.

Command an Army Codes: The Fastest Gem Burst

Redeeming codes is technically the quickest way to get a burst of gems — you can enter several in a row and instantly collect the rewards. The catch is that codes aren't farmable; once they expire, they're gone.

Here are the working codes as of early October 2026, verified by major outlets like Eurogamer's Command an Army codes page:

That's roughly 4,400 gems available right now from codes alone — enough for several multi-pulls.

How to Redeem Codes

1. Launch Command an Army in Roblox.
2. Complete the tutorial and claim your starter units if you haven't already.
3. Click the Code button on the right side of your screen.
4. Type or paste your code into the field and hit CLAIM.

Where New Codes Come From

New codes are typically announced in the game's official Discord server, but they're scattered across multiple channels. The Command an Army Roblox group page also posts updates. Bookmarking a dedicated codes tracker is the simplest way to catch drops before they expire — expired codes so far include RANKED, GUILD, PARRY, RAPIER, OPTIMIZE, WAR, RELEASE, SORRY, CONQUER, and SHIELDBREAKER.

Daily and Weekly Quests: The Consistent Grind

If codes are the sprint, quests are the marathon. According to community guide videos, completing your daily and weekly quests is the best method for consistent gem farming because the missions reward gems and account EXP at the same time — you're progressing in two ways at once.

Weekly quests take longer to finish, but some individual missions pay out over 300 gems. Daily quests are quick and usually just involve playing matches as you normally would — kills, captures, and wins all count toward progress.

Key tip: Daily quests refresh at midnight local time. If you let them sit, you're leaving free gems on the table every single day.

Battle Farming: How to Maximize Gem Payouts

Battles are the most repeatable gem source in the game. Your payout depends on how much you actually contribute, so passive play earns noticeably less than active play. Player experience suggests the difference is significant — AFK farming nets around 150 gems per match, while playing actively can yield 200 to 350+ gems.

Choose Attacker, Not Defender

Community testing shows attackers earn more gems than defenders, even when both win. In one recorded match, a defender victory paid out only 200 gems, while attacker wins in similar conditions reached 241–351 gems. If you're actively playing, always queue as attacker.

Make the Match Last Longer

This is the single most important battle trick: don't win too early. Gem rewards scale with match duration and score. If you capture the flag in the first minute, you walk away with scraps. Instead:

• Rack up kills on NPC units and enemy troops.
• Capture camps and objectives for score.
• Wait until roughly 30 seconds remain, then claim the flag (capturing takes about 15 seconds).

One player reported earning 241 gems from a match where they failed to capture the flag at the end — because the long fight generated so many kills. A clean late capture would have pushed that closer to 350.

Let Your NPCs Tank First

Don't throw your units into a fight alone. Send your NPC allies in first, then commit your own troops while the enemy is distracted. This preserves your units, generates more kills, and levels them up faster — kills feed both your score and your unit XP.

Use Cannons on Fortress Maps

On maps like Castle and Fortress, cannons deal heavy damage to clustered enemies. Grabbing a cannon early can swing a fight and pad your kill count, which directly boosts your end-of-match gem payout.

The AFK Method (If You Must)

If you want gems with minimal effort, queue as defender, summon your units, send them at the nearest camp, and then go AFK for about five minutes. You'll earn roughly 150 gems per match. It's less efficient than active play, but it works — and being defender means you won't lose the match while idle, unlike attackers who must actually capture flags.

Gem Farming Methods Compared

For free-to-play players, the ideal loop combines all the free methods: redeem codes the moment they drop, clear dailies before reset, chip away at weeklies, and farm battles actively whenever you have time to play properly.

Server Selection Tricks for Easier Wins

Winning matters, and winning is easier when your opponents aren't trying. Community players recommend joining servers with the fewest players listed in the server browser. "Bacon" accounts — newer or inactive players — are frequently AFK, which means you can often find near-empty servers where you can farm kills and objectives uninterrupted.

If an opponent does show up, don't panic. Play aggressively: contest camps early, interrupt their summons by standing near their spawn points, and use cannons to whittle down their units. The player who plays annoyingly usually wins — and the loser often rage-quits, handing you a free win and full gem payout.

Should You Buy Gems With Robux?

The Robux store sells gem packs directly, plus Luck Potions that boost your odds of pulling higher-tier units before a summon session. If you're committed to staying free-to-play, skip both — the methods above generate plenty of gems over time. But if you want a shortcut, Luck Potions paired with a big summon session are the most value-oriented purchase, since better pulls mean fewer wasted gems chasing duplicates.

Putting It All Together

The most efficient Command an Army gem routine looks like this:

1. Redeem every working code immediately — that's your biggest instant boost.
2. Clear daily quests before the midnight reset, every day.
3. Work through weekly quests for the 300+ gem payouts.
4. Farm battles as attacker, stretch matches long, and win late.
5. Fall back on AFK defender farming when you're short on time.

Stay consistent with that loop and you'll build gems fast enough to summon regularly — no Robux required.
