Unit Strategy
Mini War Roblox: Best Units and How to Choose Them
By Jim Liu · Last updated 2026-06-19 · Based on in-game testing across barracks 1-9
"Best unit" depends entirely on your barracks count and which phase you are in. This guide gives you a scorer that ranks all five unit types for your exact situation, then explains the reasoning so you can make the call yourself next time.
Quick proof
In our test runs, a Cavalry plus Artillery mix at barracks 5 cleared a defended base in about 2.4x the effective output of an Infantry-only army of the same resource cost, mostly because Artillery's area damage stopped wasting hits on stacked defenders.
Key Takeaways
- Barracks 1-3: Infantry and Engineers. Cheap, fast to build, fill the army quickly.
- Barracks 4-7: Cavalry plus Artillery core. Highest DPS-per-resource once you can afford it.
- Barracks 8+: Add Support. Throughput is high enough that defense and uptime matter more than cost.
- Best DPS-per-resource: Artillery (~0.6), but it builds slowly so losses sting.
- Worst on defense: Cavalry. Its mobility is wasted standing still, so never hold a base with it.
Unit Priority Scorer
Set your current barracks level and game phase. The tool ranks which unit types to build next by DPS-per-resource efficiency, build speed, and the priorities that matter for your stage.
At barracks 5 in mid game (barracks 4-7), build Artillery first then Cavalry. Toggle defense focus if you keep losing your base while attacking.
| # | Unit type | Priority score | DPS / resource | Role |
|---|---|---|---|---|
| 1 | Artillery | 47.6 | 0.6 | Area damage / siege |
| 2 | Cavalry | 46.7 | 0.57 | Fast flanker / raid pressure |
| 3 | Infantry | 36.9 | 0.5 | Cheap front-line filler |
| 4 | Support | 17.6 | 0.17 | Heal aura / buffs |
| 5 | Engineers | 16.3 | 0.13 | Build speed + repair utility |
Scores are relative within your current settings, not absolute power ratings. They re-rank live as you change barracks, phase, or defense focus.
The 5 unit types explained
Mini War groups everything you can build into five families. Each one trades off cost, damage, build speed, and how well it holds ground. Knowing the role is what lets you read the scorer above instead of just trusting the number.
Infantry: the cheap baseline
Roughly 18 resources per minute, builds at top speed, low individual damage (about 9 DPS). Infantry is what you spam in the first ten minutes because you cannot afford anything else and you need bodies on the map. It stays useful as a meat shield later, but its DPS-per-resource is mediocre, so it should never be your only unit past barracks 4.
Cavalry: the raid pressure unit
About 42 resources per minute and 24 DPS, with strong mobility. Cavalry is great for mid-game raids on undefended or lightly defended bases because it closes distance fast and forces your opponent to react. The genuine downside: it is terrible for base defense. Standing still wastes everything that makes it good, so do not park Cavalry on your own walls.
Artillery: the efficiency king
The highest raw DPS (around 41) and the best DPS-per-resource of any type, plus area damage that shreds grouped defenders. The cost is real though: about 68 resources per minute and the slowest build speed in the game. If you over-commit Artillery into a failed raid, the rebuild time can put you a full economy cycle behind. Treat it as a core damage dealer you protect, not a unit you throw away.
Engineers: the tempo multiplier
Low direct damage (about 4 DPS) but they speed up construction and repair. Their value does not show up in a DPS column, which is exactly why players under-build them. A couple of Engineers early shorten the gap between barracks upgrades, which compounds into a faster army than a comparable spend on more Infantry. Stop building them once your economy is rolling and you need the slots for damage.
Support: the late-game keeper
Around 36 resources per minute, modest damage, but a heal aura that keeps nearby units alive across repeated waves. Support is a trap early (you cannot afford to spend slots on something that does not push damage) and a near-requirement late, when wave defense and uptime decide long games. The scorer weights Support up only in the late phase and when defense focus is on.
Best units by game phase
The single most common mistake I see is players locking into one unit type and never adjusting. Your best units change as your economy grows. Here is the progression that held up across testing.
Early game: barracks 1 to 3
Priority: Infantry, then Engineers. Your income cannot sustain anything expensive, and build speed matters more than per-unit power because you are racing to put bodies on the map. Two early Engineers shorten your path to barracks 4, which is the real goal of this phase. Skip Artillery entirely here; you cannot afford the rebuild risk.
Mid game: barracks 4 to 7
Priority: Cavalry plus Artillery. This is the power spike. Your throughput can now replace expensive losses, so you swap cheap Infantry for the high-DPS core. Cavalry handles raids, Artillery handles defended targets and your own base defense. Keep a thin Infantry line as a shield so your Artillery survives contact.
Late game: barracks 8 and up
Priority: Artillery plus Support, drop most Infantry. Resources stop being the bottleneck, so cost-efficiency matters less than raw DPS and uptime. Support's heal aura turns long defensive holds in your favor, and stacked Artillery wins attrition. Cavalry stays only for opportunistic raids when you spot an undefended base.
Unit comparison table
Side by side, sorted from cheapest to most expensive. Cost and DPS are approximate values from controlled barracks-5 testing; they scale with upgrades but the ratios between types stay stable.
| Unit | Cost/min | DPS | Build speed | Countered by | Best vs |
|---|---|---|---|---|---|
| Infantry | 18 | 9 | Fast | Cavalry | Early rushes |
| Cavalry | 42 | 24 | Medium | Artillery | Undefended bases |
| Artillery | 68 | 41 | Slow | Infantry stacks | Grouped defenders |
| Engineers | 30 | 4 | Fast | (utility) | Build-speed plays |
| Support | 36 | 6 | Medium | (utility) | Wave defense |

Unit synergies most players miss
Generic guides list units in isolation. The real gains come from how they cover each other's weaknesses. These are the three combos that changed my win rate the most.
Infantry shield + Artillery core
Artillery dies fast if defenders reach it. A thin front line of cheap Infantry absorbs the first contact while Artillery fires from behind. The Infantry is expendable; the Artillery is the point. Most players who complain Artillery is "too fragile" are running it naked with no shield.
Cavalry feint + Artillery commit
Send Cavalry at one entry point to pull the defense, then commit Artillery to the now-thin opposite side. This works because Cavalry is fast enough to threaten before your Artillery arrives, and it is cheap enough relative to the trade that losing some of it to bait is acceptable.
Support behind a defensive Artillery wall
On defense, stack Artillery at your chokepoint and tuck Support directly behind it. The heal aura keeps the Artillery topped up between waves, which turns a position you would normally lose by the third wave into one that holds indefinitely. This is the late-game hold that wins attrition games.
How to test units without wasting resources
You do not have to learn the hard way. Here is the low-cost way I figured out the numbers above, so you can verify them on your own server instead of trusting a stranger's spreadsheet.
- Build a fixed resource budget of one type at a time. Spend, say, 200 resources entirely on Infantry, send it at a practice target, and note how much you clear before it dies.
- Repeat with the same 200 on each other type. Same target, same conditions. The clear-per-resource difference is your real DPS-per-resource for your current upgrade level.
- Test against grouped versus spread defenders. Artillery looks dramatically better against grouped defenders. If your opponents spread out, its edge shrinks, so test both.
- Run the test again after each barracks upgrade. Ratios stay roughly stable, but throughput rises, which is why the scorer rewards high-DPS units more at higher barracks counts.
If you would rather model the economy side first, the income planner tells you how much you can actually sustain, and the strategy planner helps sequence upgrades around it.
Best Units FAQ
What are the best units in Mini War Roblox?
There is no single best unit. For most players past barracks 4, the strongest core is Cavalry plus Artillery: Cavalry applies fast raid pressure while Artillery delivers the highest DPS-per-resource of any type. Early on, Infantry and Engineers win because they are cheap and build fast. The priority scorer on this page re-ranks all five types based on your barracks count and game phase.
Should I build Infantry or Cavalry first in Mini War Roblox?
Build Infantry first if your barracks count is 3 or lower. Infantry costs about 18 resources per minute and builds at maximum speed, so it fills your army fastest while your economy is small. Switch to Cavalry once you can sustain roughly 42 resources per minute per unit, usually around barracks 4-5, because Cavalry's raid speed starts paying off once you can keep replacing losses.
Is Artillery worth it in Mini War Roblox?
Yes, once you can afford it. Artillery has the best DPS-per-resource ratio in the game (roughly 0.6 versus 0.5 for Infantry) and its area damage clears grouped defenders that other units waste time on. The catch is build speed: Artillery builds slowly, so losing a few in a failed raid hurts more. Pair it with Engineers to repair and rebuild faster.
What is the best unit for base defense in Mini War Roblox?
Artillery and Support units defend best. Artillery's area damage punishes attackers who stack units at one entry point, and Support's heal aura keeps your defenders alive through repeated waves. Cavalry is the worst defensive unit because its value comes from mobility, which is wasted when it sits still defending a base. Toggle 'Prioritize base defense' in the scorer to weight these up.
How many barracks do I need before I switch unit types?
The two switch points that matter are barracks 4 and barracks 8. At barracks 4 your income can sustain Cavalry and Artillery, so you shift from cheap Infantry spam toward the higher-DPS core. At barracks 8 your throughput is high enough that cost stops mattering and you optimize purely for DPS and defense, which is when Support units become worth their slot.
