Siege Warfare Tactics

Mastering siege warfare in Age of Empires IV is crucial for breaking through heavily fortified enemy positions and securing victory. This detailed guide will walk you through effective strategies, unit compositions, and tactical considerations to dominate the battlefield.

I. Early Game Pressure: The Ram Rush

The Ram Rush is a potent early-game strategy, particularly effective against opponents who neglect walling or tower defenses. It focuses on quickly deploying Rams to destroy key economic or military structures.

Feudal Age (Age II) Objective: Reach Feudal Age quickly to unlock Rams.
Unit Composition:
- Rams (2-4): Produced at the Siege Workshop. Prioritize upgrading "Battering Ram" technology for increased health and damage.
- Spearmen (8-12): Produced at the Barracks. Essential for protecting your Rams from melee units, especially Horsemen.
- Archers (6-10): Produced at the Archery Range. Provide ranged support against enemy units attempting to engage your Spearmen or Rams.
Walkthrough Steps:
1. Economic Setup: Aim for a strong economy with at least 2-3 Town Centers producing Villagers. Gather sufficient Food and Wood to sustain unit production.
2. Age Up: Research the Feudal Age as soon as possible. Consider a landmark that provides economic or military advantages, such as the Abbey of Kings for English or the School of Cavalry for French.
3. Siege Workshop: Immediately construct a Siege Workshop upon reaching Feudal Age.
4. Ram Production: Begin producing Rams. Queue at least two initially.
5. Escort Units: While Rams are building, train Spearmen and Archers from your Barracks and Archery Range.
6. Target Selection: Identify a vulnerable enemy structure. Early targets often include:
  - Outposts/Towers: Eliminating these reduces enemy vision and defensive capabilities.
  - Barracks/Archery Ranges: Disrupts enemy unit production.
  - Town Center: A high-risk, high-reward target that can cripple their economy.
7. Execution: Move your Rams forward, using your Spearmen to screen against melee threats and Archers to target enemy ranged units or Villagers attempting to repair. Focus all Rams on a single target for maximum efficiency.
Countering the Ram Rush:
- Walls: Early stone walls can significantly delay a Ram Rush.
- Outposts/Towers: Garrisoned units in towers can deal considerable damage to Rams.
- Horsemen: Effective against Spearmen, allowing them to flank and destroy Rams.
- Repairing Villagers: Micro-managing Villagers to repair damaged structures can buy crucial time.

II. Mid-to-Late Game Siege: Breaking Fortifications

As the game progresses, enemy defenses become more formidable, requiring a more diverse and powerful siege arsenal. This phase focuses on utilizing advanced siege engines to dismantle strongholds.

Castle Age (Age III) and Imperial Age (Age IV) Objective: Deploy advanced siege units and coordinated attacks.
Key Siege Units:
- Mangonels: Produced at the Siege Workshop. Excellent for area-of-effect damage against grouped units and light structures. Upgrade "Mangonel Reload Speed" for faster attacks.
- Springalds: Produced at the Siege Workshop. High single-target damage, ideal for destroying enemy siege weapons and heavily armored units. Research "Springald Range" for increased effectiveness.
- Bombards: Produced at the Siege Workshop (Imperial Age). The ultimate anti-building weapon, capable of quickly leveling stone walls and Keeps. Prioritize "Bombard Range" and "Bombard Damage" upgrades.
- Trebuchets: Produced at the Siege Workshop (Imperial Age). Long-range siege weapon, effective against static defenses from a safe distance. Requires setup time.
Strategic Deployment:
1. Scouting: Use Scouts or fast cavalry to identify weak points in enemy defenses, such as undefended wall sections or areas with fewer Keeps.
2. Siege Line Formation: Position your siege units carefully.
  - Front Line: Place Rams (if still viable) or melee units to absorb damage.
  - Mid Line: Mangonels for clearing enemy units and Springalds for counter-siege.
  - Back Line: Bombards and Trebuchets for targeting walls and Keeps.
3. Combined Arms: Never send siege units alone. They are vulnerable and require protection.
  - Melee Infantry (e.g., Men-at-Arms, Spearmen): Protect siege from enemy melee units.
  - Ranged Units (e.g., Crossbowmen, Arbalesters): Provide cover fire against enemy ranged units and garrisoned defenses.
  - Cavalry (e.g., Knights, Lancers): Can flank enemy forces or quickly eliminate exposed siege weapons.
4. Focus Fire: Concentrate all siege weapon fire on one target at a time. Destroying a wall segment completely opens a breach faster than spreading damage.
5. Breaching and Pushing: Once a breach is made, immediately send in your melee units to engage defenders and create a path for your ranged and siege units to push through.
6. Repair and Replenish: Keep Villagers nearby to repair damaged siege engines. Continuously produce replacement units from your Barracks, Archery Ranges, and Stables to maintain pressure.

III. Defensive Siege Tactics

Siege units aren't just for offense; they are vital for defense as well. Utilizing them effectively can turn the tide of an enemy assault.

Counter-Siege:
- Springalds: Your primary tool for destroying enemy siege weapons. Position them strategically behind walls or on high ground for maximum range and protection.
- Mangonels: Effective against massed enemy infantry attempting to push through a breach or besiege your structures.
Fortification:
- Keeps: Construct Keeps at strategic choke points or near vital resources. Upgrade "Keep Emplacements" for increased defensive capabilities.
- Walls: Stone Walls are essential for slowing down enemy advances. Upgrade "Fortified Outposts" and "Stone Wall Towers" for added defense.
- Garrisoning: Always garrison ranged units (Archers, Crossbowmen) in Keeps and Towers to maximize their defensive output.
Repair Teams: Keep a dedicated group of Villagers ready to repair damaged walls, Keeps, and siege engines during an enemy assault. Assign them to a control group for quick access.
