Purpose

Unlocked after upgrading their Headquarters to Level 3, the Alliance Centre allows the player to join an existing alliance with other players or form their own.

Once joined (or created), players within that alliance can request for off-map calldown supports researched at the Operation Planning, "visit" each other's bases, view their profiles, or be challenged to mock training battles where you can test your strategies on each other's bases.

However, it should be noted that while neither player in the training battle will lose units, operations, or need to rearm their traps afterwards, they do not gain Victory Points even if the attacking player destroys enough buildings to gain stars (or the defender holds out long enough to win). Resource depots built by the defending player also cannot be looted in this mode.

The Centre also serves as a rudimentary defensive structure, as any supports that you receive from fellow members can be used to defend your base during attacks in online matches. While its calldown range is actually quite short (it has almost the same amount of range as the AT Launcher), depending on the type of support that you receive, the Alliance Centre can be a fairly powerful defence; in no small part due to having a large amount of hit points as well.

The Alliance Centre only supports one calldown initially, but once upgraded can contain up to six off-map supports at a time. Just like how traps must be rearmed manually at a cost, support powers stored at the Centre do not regenerate, and must be re-requested from other alliance members once they are used in a defensive battle.

Supported Operations

Further upgrades (to the Centre itself and not the donated operations) will increase the "attack range" of the Alliance Centre. Anything that enters this zone will trigger the Centre to calldown a support on that unit's location.

NOTE: Except for the Rescue Operation and UAV Drone, all other offensive support powers can be donated to alliance members regardless of their Headquarter's/Operation Planning's upgrade level; provided that they have enough slots left at their Centre to store them.

Icon	Name	Effect	Notes
	Artillery Support	- Calls in an artillery strike on the nearest enemy unit - Bombards it with 6 shells in a circular area-of-effect	- Damage dealt depends on the upgrade level of the operation - Shells do not damage your own structures - Will not be used or have any effect against flying units
	EMP	- Disables all vehicles in the affected area for 4 seconds	- Does not affect infantry squads - Does not affect your own structures - Duration length depends on upgrade level of operation
	Helicopter Support	- Calls in a gunship to strafe the nearest enemy unit in a linear direction	- Randomly targeted, but prefers groups of units - Does not attack aircraft - Will not damage your structures - Damage inflicted varies depending on upgrade level
	Smart Bomb	- Drops a laser-guided bomb on the nearest enemy unit	- Will target infantry squads (but not aircraft) - Cannot damage your own structures - Damage amount depends on upgrade level of operation

Notes

• Due to the termination of Mobile Ops' online services on May 4th, 2022, the Alliance Centre's online features no longer work as intended. This article's information is based on the structure's intended design prior to the server shutdown.

Trivia

• Bases that have an Alliance Centre equipped with a support can usually be countered by simply sending a single unit to get within range of it. The Centre will automatically waste its support (usually an Artillery Barrage) on the unit, which leaves the rest of your units safe from it.
• By default, the flag will always use a neutral white colour. If the player joins an alliance with a custom logo, the flag will adopt that alliance's custom flag instead.
