You pull a strong troop in Command An Army, head straight to your loadout, and the game simply refuses to let you equip it. Nothing is broken. Every troop carries a star value, and your account has a Star Limit that caps the combined star total of everything you field at once. Until that cap grows, a single expensive unit can swallow most of your budget.
Quick answer: Level up your account. The Star Limit is tied to your account level, so play matches and earn XP, then reopen the Units menu after a LEVEL UP! and check your new total before equipping the higher-star troop.
How the Star Limit works in Command An Army
Think of the Star Limit as a spending budget rather than a power rating. Each troop in your inventory is worth a set number of stars, and the Units screen adds up the stars of everything currently equipped. That running total is displayed against your ceiling, so a readout like 7/7 means the budget is spent and nothing else fits until you unequip something.
The game enforces the cap at the moment you try to equip. It does not let you go one star over and warn you later. If adding a unit would push the total past your limit, the equip simply does not happen.
Because of that, the number of bodies you bring matters as much as their quality. A cap around 6 is roughly where you have room for one extra troop alongside your main squad, which is why early rosters lean on cheaper starter units instead of a single expensive summon.
How to increase the Star Limit
There is no shop item, gamepass, or menu toggle that raises the cap. It rises with your account level, so the whole process comes down to playing rounds and collecting XP.
Note: the exact number of stars gained per level is not published by the developer, so treat each level up as a prompt to check your stats in game rather than assuming a fixed increase.
Why a new summon will not equip
Almost every failed equip traces back to the same cause. The troop’s star value plus everything already equipped exceeds your current cap. Before assuming something is wrong, unequip a cheaper body and try again, since freeing up stars is usually enough to make room.
Do not delete a high-star unit you cannot use yet. It stays in your inventory indefinitely and becomes available the moment your level raises the ceiling far enough to afford it.
Troops you can spend your stars on
Your roster comes from two places, the starter troops you choose after the tutorial and the Standard Banner summons. Starter units are the cheap bodies that keep a squad full while the cap is low, while summons are the expensive picks worth saving budget for. You can find the experience itself on the Command An Army Roblox page.
| Unit | Role | Source |
|---|---|---|
| Mercenary | All-round melee body | Starter selection |
| Shieldman | Holds ground against frontal pushes | Starter selection |
| Spearman | Reach against cavalry, defensive line | Starter selection |
| Archer | Ranged pressure from behind the line | Starter selection |
| Knight | Shock unit for gates and structures | Tutorial sequence |
| Spartan | High-value combat unit | Standard Banner summon |
| Immortal | Durable melee with staying power | Standard Banner summon |
| Crossbowman | Ranged support, higher output | Standard Banner summon |
| Scout Rider | Fast cavalry for flanks and rushes | Standard Banner summon |
The Units screen also sorts by rarity and lists each troop’s HP, DMG, SPEED, RNG, DPS, BLOCK, and RUSH DMG, which is the fastest way to compare two units competing for the same stars.
Spending the cap well while it is still small
A tight budget rewards focus. Equip the highest-value troops you can actually afford, then fill the leftover stars with cheap starter bodies so you are never walking into a round undermanned. Two or three well-developed units usually outperform a scattered mix, because the cap limits how many can be on the field anyway.
Star value is also not the same as performance. A lower-star troop that has been upgraded and ascended can beat a freshly summoned high-star unit that has had nothing invested in it. Scout Riders are the common example, staying useful well past the point where players obtain rarer options. Judge a troop by how long it survives and how quickly it clears a point, then put your upgrade resources into the units you keep bringing back.
The cap is a pacing tool more than a wall. Keep your strong summons parked in the inventory, run objectives for XP, and check the Units screen each time you level. Sooner or later the total climbs high enough that the troop you have been saving finally slots in.
