Best StarCraft II Units
Every unit in StarCraft II multiplayer, ranked by what it contributes across a whole game rather than by what it costs to build. Entries cover all three races and every tier, from 25 mineral Zerglings to capital ships that take a full economy to field, and they include workers, detectors and transports that never fire a shot. The StarCraft II units near the top are the ones that force an opponent to change plans: spellcasters that win fights outright, siege units that dictate where fights happen, and cheap bodies that stay efficient at every stage.

How this ranking works
Seed POV: Match-deciding impact weighed against cost and supply efficiency
A defensible order rewards units that change what an opponent is allowed to do, so detectors, spellcasters and siege units land above raw damage dealers, with the efficient staples that hold armies together close behind. The contentious part is the top, where a Marine or Siege Tank that appears in nearly every Terran game competes with a Disruptor or Viper that swings single fights but only exists at high tech.
As of August 2026, Battlecruiser leads Best StarCraft II Units in the community ranking.

Global Ranking

Battlecruiser
Battlecruisers fire Yamato Cannon for 240 damage, enough to erase most single targets, and Tactical Jump warps them across the map to a chosen spot. Cost is the limit, and a lone Battlecruiser still dies to massed anti-air.

Siege Tank
Siege Tanks deal 40 damage and another 30 against Armored once deployed at range 13, up from 35 and 15 in earlier versions. The entire skill is placement, since a sieged tank cannot move and a Viper's Abduct exists to punish exactly that.

Brood Lord
Morphed from a Corruptor once a Greater Spire is finished, the Brood Lord lobs Broodlings that land, fight on their own and then expire. It cannot touch air at all, which is why the Wings of Liberty version leaned so heavily on Infestor support to survive.

Carrier
Carriers cost 350 minerals and 250 gas for 6 supply and fight entirely through Interceptors, up to eight per ship at 15 minerals each. Since the hull never fires directly, damage keeps flowing while the Carrier holds maximum range.

Ultralisk
Ultralisks cleave everything in front of them, and Chitinous Plating adds 2 armor, which reduces low-damage attacks like Marines and Zealots to almost nothing. Frenzied leaves them immune to snares and stuns, so Concussive Shells and Fungal Growth do not stick.

Thor
Thors switch between Explosive Payload, splash missiles for light air like Mutalisks, and High Impact Payload, single-target Punisher Cannons with range 10 for Battlecruisers and Carriers. As Massive ground units they anchor mech but fold when a Viper abducts them.

Ghost
Ghosts carry EMP, which drains 100 energy and 100 shields across an area, and Steady Targeting, a 170 damage snipe on Biological units. They also call in the Tactical Nuke, worth 300 damage to units and 500 to buildings if it lands.

Immortal
Barrier soaks up to 100 damage the moment an Immortal takes a hit, which is why Siege Tanks and Roaches struggle so badly against them. Bonus damage against Armored targets means the exchange runs lopsided in both directions.

Marine
Marines cost 50 minerals for 1 supply, start at 45 hit points, and reach 55 with Combat Shield, which covers exactly the 10 health each Stimpack use burns. Nothing else in the game scales as hard with upgrades, Medivac healing and player control.

Mothership
Only one Mothership can exist per player, and it cloaks the units around it while carrying a recall that pulls a scattered army home. Patch 4.0 removed the Mothership Core that had stood in for it, returning the full ship to the Nexus build list.

Zealot
Zealots need no gas, land two blows per attack, and gain Charge from the Twilight Council, closing the gap before ranged units can kite them. Shields that fully regenerate out of combat let them absorb far more over a game than their cost suggests.

Reaper
Reapers jump up and down cliffs, regenerate health once they have been out of combat for a few seconds, and throw KD8 Charges that knock enemy units backward. They are designed for the first three minutes of a game rather than for any late-game army.

Stalker
Stalkers hit both air and ground with bonus damage against Armored, and Blink from the Twilight Council teleports a group short distances to escape, chase or reach a cliff. Damage per cost is mediocre, and Protoss players accept that for the mobility.

Zergling
Zerglings hatch two at a time from one larva at 25 minerals and half a supply each, so individual losses barely dent a Zerg bank. Metabolic Boost and Adrenal Glands together produce Cracklings, quick enough to overrun most unupgraded ground armies.

Baneling
Banelings morph out of Zerglings and detonate on contact for area damage with a heavy bonus against Light units, which covers workers, Marines and Zealots. Centrifugal Hooks raises their speed enough to catch a retreating bio army.

Colossus
Colossi walk up and down cliffs and rake ground units with a linear beam that Extended Thermal Lance pushes from range 7 to 9. Carrying both the Massive and Armored tags while remaining targetable by anti-air is the trade, and Vikings and Corruptors collect on it.

Disruptor
Purification Nova is the whole unit: an invulnerable orb the player drives for roughly two seconds before it detonates for heavy area damage on ground targets. One clean hit erases a bio ball, so every Disruptor fight is decided by how well units are split.

Liberator
Liberators fight air targets in flight, then transform into Defender Mode to shell a fixed circle of ground with heavy single-target damage. Advanced Ballistics from the Fusion Core lets that zone be placed from much farther away, which is what makes a Liberator line hard to approach.

Roach
Roaches regenerate fast while burrowed, and Tunneling Claws lets them crawl away underground to heal in the middle of a fight. Glial Reconstitution adds movement speed, which is what turns a cheap Armored body into a real attacking unit.

Swarm Host
Swarm Hosts send out free Locusts that attack on their own, a mechanic that produced hour-long sieges in Heart of the Swarm. Legacy of the Void rebuilt them as harassment, adding a cooldown to Spawn Locust, cutting how long each Locust lives and offering a Flying Locusts upgrade.

Viking
Vikings switch between Fighter Mode, an air-only form with long range and bonus damage against Armored targets, and Assault Mode, a ground walker. That air attack is why Terran answers to Colossi, Brood Lords and Tempests all start here.

Sentry
Sentries warp in with exactly the 50 energy a Force Field costs, so the first wall can go up immediately. Guardian Shield reduces incoming ranged damage for nearby units and Hallucination fakes an army for scouting, so the unit keeps earning its supply long after the opening.

Viper
Abduct is the reason Vipers get built, dragging a Siege Tank, Colossus or Thor into the middle of the Zerg army. Blinding Cloud cuts ranged units caught inside it down to melee range, Parasitic Bomb punishes clumped air, and Consume drains buildings for energy.

Hydralisk
Hydralisks hit air and ground hard for their cost and die instantly to splash, so their value swings entirely on positioning. Grooved Spines adds range and Muscular Augments adds speed, and massing them before both are finished rarely ends well.

Dark Templar
Permanently cloaked and melee only, Dark Templar simply end games against opponents with no detection in position. A late 2016 patch added Shadow Stride from the Dark Shrine, a short blink that closes onto workers or slips away before a scan lands.

Cyclone
Introduced with Legacy of the Void, the Cyclone is a Factory unit built around Lock On, a tracking attack that keeps damaging one target while the Cyclone backs away. Balance patches have reworked its cost, range and upgrades more often than almost any other unit.

Adept
Adepts deal bonus damage to Light units and project a Psionic Transfer shade that teleports them after 7 seconds, moving through walls of units and Force Fields. Early Protoss aggression in Legacy of the Void was built almost entirely around that shade.

Infestor
Fungal Growth roots an enemy army in place while Neural Parasite hands the Zerg player direct control of a single unit. Patch 4.11 removed Infested Terrans from the kit and replaced them with Microbial Shroud, ending the spell that defined the unit for years.

Raven
Ravens provide detection plus three tools that barely overlap: Auto-Turret, Anti-Armor Missile for stripping armor off a clumped army, and Interference Matrix. That last one shuts down a target's attacks and abilities, which can pull a Battlecruiser out of a fight entirely.

Void Ray
Void Rays swapped the charge-up beam of Wings of Liberty for Prismatic Alignment, a timed activation that adds bonus damage against Armored targets. That burst window is what lets a small flight threaten Ultralisks, Thors and Battlecruisers.

Lurker
Lurkers returned in Legacy of the Void after being absent from StarCraft II multiplayer entirely, attacking only while burrowed with a line of spines that strikes everything between the unit and its target. Seismic Spines extends their range from 8 to 10.

Queen
Queens hold Zerg together with Spawn Larvae, which adds three larvae to a Hatchery, plus Creep Tumors for map control and Transfusion for emergency healing. The range increase in patch 1.4.3 turned them into real defenders and helped set off the Brood Lord and Infestor era.

Archon
Two Templar of any kind merge into an Archon, which arrives with 350 shields over a body of just 10 hit points and splashes both air and ground. Bonus damage against Biological targets makes it a blunt answer to Zergling and Baneling floods.

Marauder
Marauders deal bonus damage to Armored units and slow whatever they hit once Concussive Shells is researched, which is why Roach and Stalker pushes stall against bio. Paired with Marines and Medivacs they form the standard Terran ground army.

Phoenix
Phoenixes attack while moving, which lets them kite Mutalisks that would otherwise trade evenly, and Anion Pulse-Crystals adds 2 range on top of that. Graviton Beam lifts a non-Massive ground unit out of reach, removing a Siege Tank from a fight for the price of energy.

Mutalisk
Mutalisks fire Glaive Wurms that bounce to two further targets for a third of the damage each time, so tight enemy clumps take far more than the listed figure. Fast regeneration out of combat lets a damaged flock retreat, heal and come back.

Corruptor
Corruptors shoot air only, with bonus damage against Massive targets that makes them the Zerg answer to Colossi, Carriers and Battlecruisers. Caustic Spray channels heavy damage into a structure, and any Corruptor can morph into a Brood Lord.

Banshee
Banshees attack ground only and can cloak, forcing every opponent to keep detection in position or lose a base to a pair of them. Hyperflight Rotors raises their speed from 3.85 to 5.25, which makes a cloaked harassment squad hard to chase.

Observer
Observers are permanently cloaked flying detectors from the Robotics Facility, and Surveillance Mode roots one in place in exchange for a wider sight radius. Protoss builds that skip one lose outright to Dark Templar, Banshees and burrowed Widow Mines.

Warp Prism
Phasing Mode turns the Warp Prism into a mobile power field, letting Gateways warp reinforcements straight into an enemy base. Legacy of the Void also extended its pickup range, so a careful pilot can lift an Immortal or Sentry out of a losing fight.

Ravager
Corrosive Bile lands after a delay at range 9 and breaks Force Fields, which changed how Zerg armies handle Protoss ramps and walls. Ravagers morph from Roaches, so the ability arrives early enough to matter in the opening minutes.

Medivac
Medivacs heal Biological units continuously and transport ground forces including Siege Tanks and Thors, while Ignite Afterburners provides a burst of speed for drops. Every standard Terran bio attack is designed around what a Medivac can carry.

High Templar
Psionic Storm and Feedback do opposite jobs for the same unit, one punishing clumped ground armies and the other destroying energy-based casters outright. When a High Templar runs dry, two of them merge into an Archon instead of being wasted.

Oracle
Oracles activate Pulsar Beam for 25 energy plus a drain each second, long enough to shred a mineral line before detection arrives. Revelation exposes an area of the map and Stasis Ward traps ground units, giving the unit value after the harassment window closes.

Hellion
Hellions spray a line of fire that carves through workers and Zerglings, and Infernal Pre-Igniter pushes that damage higher against Light targets. Speed is the real weapon, letting a pair run past defenses into a mineral line and back out.

Hellbat
Hellbats are Hellions transformed at an Armory into a slower Biological brawler with a cone of flame, and Infernal Pre-Igniter adds a large bonus against Light. Being Biological means Medivacs can heal them while they soak hits for Marines.

Widow Mine
Widow Mines burrow and fire Sentinel Missiles for 125 damage plus 35 against shields, with splash that deletes any clump that was not split. They reload instead of dying on use, so one surviving mine keeps threatening the same patch of ground.

Tempest
Tempests outrange nearly everything that could shoot back, and their air attack carries bonus damage against Massive targets like Brood Lords and Battlecruisers. Low damage for a heavy gas price makes them a siege and denial tool rather than a brawler.

Probe
Probes warp structures in rather than building them by hand, so the worker can return to mining while the building finishes on its own. That single difference is why Protoss economies recover from harassment differently than Terran or Zerg.

SCV
SCVs stay locked to a structure for its full build time, the least flexible worker mechanic of the three races, but they also repair buildings, Siege Tanks, Battlecruisers and each other. Repair is why Terran mech holds ground other armies cannot.

Drone
Because Drones are consumed when they morph into structures, every Zerg building costs a worker as well as minerals. That trade defines Zerg macro: droning through a timing attack wins long games and loses short ones.

Overseer
Overseers are morphed Overlords that gain detection, spawn Changelings for scouting, and can sit in Oversight mode for a wider sight radius. Zerg has no other mobile detector, so Phoenixes and Vikings hunt them first.

Overlord
Overlords cost 100 minerals and provide 8 supply each, so Zerg pays for population with units that also scout and, with Ventral Sacs, carry troops. Forgetting to make them is the most common cause of a stalled Zerg economy at any skill level.

Broodling
Broodlings are thrown rather than built, spawning from Brood Lord attacks to fight on their own before dying on a timer regardless of health. Their real job is blocking, since a wall of them stalls ground units trying to reach the Brood Lords.

Interceptor
At 15 minerals apiece, Interceptors are the Carrier's actual weapon, drones that fly out, strike and return to the hull. They cost no supply and can be rebuilt after losses, so a Carrier that survives an engagement is only briefly out of the fight.
