Shogun 2 Units Guide: Rosters, Counters and Roles
How every Shogun 2 unit family works — ashigaru, samurai, monks and cavalry roles, the counter system, matchlocks and siege units explained for army building.
Shogun 2's battles read like rock-paper-scissors played with steel: every unit family exists to do one job and dies to another. This units guide covers the families — ashigaru, the samurai disciplines, warrior monks, cavalry and gunpowder — and the counter-grammar that turns a roster into an army.
Ashigaru: The Line That Holds
Ashigaru are conscripts with polearms and bows, and they are not filler — they are the frame of every army. Yari ashigaru in wall formation stop cavalry dead and hold ground far above their price; bow ashigaru supply volume fire that forces movement; matchlock ashigaru, unlocked later, deliver volleys that break anything stationary. Their weakness is morale: ashigaru rout under flanking and sustained melee, so your job as general is to keep them fronted, supported and inspired. An army of ashigaru with a good general is the most cost-effective force in the game.
Samurai: The Hammers
Katana samurai are line-breakers — supreme in melee, vulnerable to cavalry and massed yari. Yari samurai trade killing power for all-round resilience and anti-cavalry duty, the flexible spine of mid-game armies. No-dachi greatswordsmen are pure shock for charge-timing players. Bow samurai outclass ashigaru archers at range and dueling. The samurai lesson: expensive does not mean universal — each discipline is a tool, and tools win when applied to their matching problem.
Warrior Monks: Inspiration With a Staff
Monk units — naginata and bow devotees — fight hard and, critically, inspire nearby troops and hold morale when the tide turns. They cost dearly and punish careless placement, but a monk anchor turns a shaky line into a fortress. Uesugi's campaigns are built entirely on this family.
Cavalry: The Arriving Argument
Yari cavalry hunts flanks, routers and enemy horse; katana cavalry charges home against infantry flanks; great guard heavy cavalry is a late-game hammer of legend. Cavalry's rule is patience — committed early into a prepared line it dies, committed late into a stretched one it wins the battle in thirty seconds. Light cavalry also serves as the map-control arm, running down routers so they never return.
Gunpowder and Siege
Matchlock units transform the late game: volleys shred frontal approaches and shatter morale, in exchange for weather dependence and vulnerable reloading windows. Siege equipment and fire arrows crack the castles that garrison Shogun 2's chokepoint campaigns — a besieger's arsenal is half the siege battle before walls are even touched.
The Counter Grammar
Yari beats cavalry. Cavalry beats bows and flanks. Katanas beat yari fronts. Bows force movement; matchlocks punish it. Naginata hold anything. Monks hold and inspire. Every deployment decision in Shogun 2 is this table applied to terrain — and every rout you suffer is a row you ignored. The army composition guide builds full stacks from these pieces.
FAQ
Are samurai worth the upkeep? As hammers and duelists, yes; as line filler, never — ashigaru hold, samurai swing.
What beats warrior monks? Massed missile fire and cavalry flanks — never frontal yari grinding.
Do matchlocks replace bows? No — they complement: bows sustained, matchlocks punctual.
