Military buildings drive combat progression in Mini War, the Roblox country-conquest game by M&M Community. Each structure deploys its own set of units, scales in price, and sits in a rarity band that runs from Common starter towers to Divine and Limited endgame hardware. You buy them from the in-game build menu using cash earned by your economy, and most can also be unlocked instantly with Robux.
Quick answer: The cheapest military building is the Border Tower at $150, and the most expensive cash-priced building is the Air Fortress at $150B. Pentagon and Sci-Fi Tank Hangar are Limited and come only from the Veteran Crate and Prototype Crate, not direct cash purchase.

You can buy and play the game from the official Mini War page on Roblox. Robux purchases unlock buildings instantly, but the top tiers cost a steep amount, so many players grind in-game cash for Mech Station, Rocket Bunker, and above instead.

Early-game military buildings
At the start, keep military spending cheap and route most of your cash into income buildings. A few low-cost defenses protect your base while the economy ramps up.
- Border Tower ($150) is the cheapest guard and covers key entrances against solo raiders.
- Barracks ($750) provides reliable infantry for early defense and small pushes.
- Sniper Tower ($4K) adds long-range support and helps clear infantry waves.
Mid-game military buildings
Once income is stable, you can field vehicles, tanks, and air support. Mid-game fights usually come down to balancing armor, infantry, and helicopters.
- Vehicle Base ($8K) gives fast, mobile units for patrol and scouting.
- Tank Base ($25K) puts armored frontline units that absorb damage and push objectives.
- Helipad ($140K) adds air cover and faster strikes for hit-and-run play.
- Special Force ($300K) brings heavy-firepower infantry with mixed loadouts.
Endgame military buildings
Late-game battles shift to missiles, bombers, artillery, and futuristic units with huge health pools. These structures carry long build times, so plan upgrades around active sessions and offline protection.
- Missile Launcher ($4.5M) delivers heavy burst and area denial behind tank lines.
- General’s Base ($10M) sends 5 B2 Bombers for strikes on fortified positions.
- Air Base ($50M) deploys 2 Black Hawks, the strongest invasion tool in the current meta.
- Artillery Depot ($250M) fields Rocket Tanks for long-range fire.
- Rocket Bunker ($5B), Mech Station ($25B), Spider Base ($75B), and Air Fortress ($150B) are the top-end Secret and Divine slots with the highest HP units in the game.
Note: Combine a Military Hospital with expensive units to keep them alive longer through its Ambulance support. Air units also cover more ground quickly, so they can pressure multiple borders at once.
How to unlock military buildings
Most structures are direct buys from the build menu using in-game cash, with cheap starters available immediately and advanced bases unlocking as your income tiers climb. Pentagon and Sci-Fi Tank Hangar are the exception. They drop only from the Veteran Crate and Prototype Crate, both purchased with Robux.
Every cash-priced building can also be bought outright with Robux to skip the grind. Because high-end costs run into the thousands of Robux for Mech Station, Spider Base, Air Fortress, and similar, grinding cash through Farms, Oil Refineries, and territory multipliers is the cheaper route to a full army. Redeeming any active codes before you spend can also give free boosts toward those purchases.
