Unit Counters & Combat Guide
Battles in Age of Empires II: Definitive Edition depend on hard mathematical counter multipliers. Outputting raw numbers will fail if your army composition matches up poorly against your opponent's unit choices.
The Rock-Paper-Scissors Counter Triangle
Understanding primary counter dynamics prevents wasteful military trades.

Counters Counters
Archers/Siege Spearmen
| Main Unit Class | Primary Hard Counter | Secondary Counter | Weak Against |
|---|---|---|---|
| Cavalry (Knights/Scouts) | Spearmen (+15 vs Cav) / Pikemen (+22 vs Cav) / Halberdiers (+32 vs Cav) | Camels / Heavy Camels | Massed Archers, Monks |
| Archers (Crossbows/Arbalests) | Skirmishers / Elite Skirmishers | Mangonels / Onagers | Cavalry (in open ground) |
| Infantry (Militia/Longswords) | Archers / Hand Cannoneers | Scorpions / Chokepoints | Cavalry, Siege Engines |
| Siege (Mangonels/Scorpions) | Light Cavalry / Knights | Eagle Warriors | Massed Ranged Fire, Bombard Cannons |
| Monks | Light Cavalry / Eagles | Skirmishers | Heavy Mass Charges |
Counter Exceptions: Cataphracts and Sicilians
Do not assume Halberdiers counter all mounted units automatically.
- Byzantine Cataphracts: Possess +12 Cavalry armor, negating 12 points of the Halberdier's +32 bonus damage. Counter Cataphracts with massed Arbalesters or Champions instead.
- Sicilian Units: Innately resist 40% of all incoming bonus damage across all armor classes, significantly reducing the impact of counter units.
Gold Units vs Trash Units
Military units fall into two distinct economic categories: gold-costing power units and gold-free trash units.
Gold Units (Power Core) Trash Units (Gold-Free Support)
├── Knights / Paladins ├── Spearmen / Halberdiers
├── Crossbows / Arbalests ├── Skirmishers / Elite Skirmishers
└── Mangonels / Trebuchets └── Scout Cavalry / Hussars
- Gold Units: Expensive units like Knights, Crossbowmen, and Siege Engines cost Gold alongside Wood or Food. They possess high base statistics and dominant combat scaling.
- Trash Units: Spearmen, Skirmishers, and Scout Cavalry cost zero Gold. They act as targeted counters to specific gold units.
- Economic Strategy: Spend Gold during early and middle game power spikes. Transition into trash unit compositions when primary map gold veins run dry during late Imperial battles.
High Ground and Terrain Advantages
Elevation alters damage math significantly.
Attacker on High Ground ──> +25% Damage Dealt ──> Defender on Low Ground
Defender on Low Ground ──> -25% Damage Dealt ──> Attacker on High Ground
- Hill Bonus (+25% / -25%): Units positioned on elevated terrain deal 25% extra damage to lower targets, while units firing upward suffer a 25% damage penalty. This creates a net 66.66% mathematical advantage for the high-ground position. Tatars deal an upgraded +50% damage from high ground, while Georgians suffer 40% less damage when defending on lower terrain.
- Cliff & Forest Chokepoints: Funneling large cavalry armies through narrow tree passes negates their numerical advantage. Position archers or mangonels behind natural barriers to punish clumped units.
- Building Cover: Ranged units taking fire can retreat under the garrison umbrella of a Town Center or Castle to gain free defensive firepower while protected inside.
Essential Combat Micro Techniques
Control mechanics can swing unfavorable engagements in your favor.
Stutter Step: Right-click move ──> Stop key (S) / Attack ground ──> Fire salvo ──> Move
1. Archer Stutter-Stepping (Kiting)
Order your ranged squad to fire a salvo, click backwards to retreat while their attack animation resets, then stop and fire again. This keeps melee cavalry from closing distance while taking continuous damage.
2. Mangonel Attack Ground
Do not target individual moving infantry units with a Mangonel. Instead, select Attack Ground (T) and click the spot on the ground where the enemy army will walk two seconds in the future. A well-placed boulder hit can wipe out 15 archers instantly.
3. Monk Conversion RNG Mechanics
Monk conversions do not operate on a simple flat timer. Upon starting a conversion, a mandatory 5-second immunity interval must elapse (increased to 8 seconds for Scout Cavalry and structures). After this immunity phase, the engine runs a 38% probability check per interval, guaranteeing conversion by the 9th interval (or 10th for resistant units). Starting a conversion on a building charges these conversion intervals, and switching targets mid-stream to an approaching Knight applies the accumulated time instantly.
4. Split Formation vs Area Damage
When facing enemy Mangonels or Onagers, select your army and tap X to split into a spread formation right before impact. Re-group with E once the projectile lands safely away from your troops.
5. Stop Micro for Melee Pathing
Melee units in large battles often gridlock or stutter when pathing around friendly units. Tapping the Stop key (S) repeatedly during melee combat forces units to immediately recalculate proximity targets, resolving pathing bugs and maximizing damage per second.
