Age of Empires Mobile: Trebuchet Siege Positioning for Level 5+ Cities

To maximize structure damage during Level 5 and higher city sieges in Age of Empires Mobile, manually command your trebuchets to target city walls from the absolute edge of their firing range while positioning high-durability frontline units between the siege engines and enemy defenses. Relying on automated movement causes trebuchets to advance into the reach of defensive towers and garrison counterattacks, leading to premature destruction.

Strategic Positioning for Trebuchet Squads

Trebuchets deal dedicated siege damage to high-HP city walls, but they lack defensive stats. Alliance leaders and siege operators must actively maneuver units rather than relying on default target orders.

Deploy a Defensive Screen: Place melee or high-survivability cavalry squads in front of your trebuchets. Enemy garrisons and defensive towers target the closest valid threat, keeping your artillery safe while firing.
Hold Maximum Attack Distance: Select trebuchet squads manually and order them to halt as soon as the target wall enters the outer boundary of their attack indicator circle.
Stagger Siege Units: Spread trebuchets slightly apart rather than stacking them in one exact location. Staggering prevents defensive area-of-effect damage from hitting all siege engines simultaneously.
Clear Line of Sight: Position squads away from large terrain obstructions or environmental obstacles that can block line of sight or break attack commands.

Managing Unit Health and Siege Rotations

High-level cities possess large structural HP pools that require sustained bombardment. Losing a trebuchet during a siege creates a severe delay for your alliance.

Monitor Trebuchet Durability: Watch individual squad health bars throughout the siege bombardment phase.
Pull Damaged Units Immediately: If defensive units or tower fire target a trebuchet squad, manually order that squad to retreat out of range before it is eliminated.
Rotate Squads: Have designated backup players or reserve squads step forward to take over the firing position while damaged trebuchets repair or recover.
Keep Focus on the Objective: Ensure trebuchet operators maintain wall-targeting orders rather than switching to defend against mobile enemy forces.

Troubleshooting Trebuchet Firing and Pathing Issues

If your trebuchets stop attacking or move dangerously close to city walls during a siege, verify the following conditions:

Issue	Root Cause	Next Action
Trebuchet moving toward wall	Unit is ordered to attack a target outside its current range circle.	Halt movement manually; reposition the squad closer to the edge of the attack boundary without overstepping defensive lines.
Engine sitting idle	Issued a move command or interrupted by combat pathing.	Re-select the trebuchet squad and manually issue a direct attack command onto the wall segment.
Pathing stuck on terrain	Uneven ground or natural obstacles blocking automated routing.	Manually guide the unit sideways around the terrain before issuing the final position and attack orders.
