Mobile Armor

"I can't sleep yet, I still have work to do..."

This article still needs to be completed. You can help us by contributing.

Mobile Armor is a vehicle system added to Girls' Frontline with client version 3.03 on 21 September 2023. Vehicles are piloted by Dolls and have the ability to both attack from the map (any enemy which is 2 tiles from the vehicle, during this phase your vehicle will not be attacked, just like a HOC unit) and participate in direct combat (like assimilated Architect or assimilated Dreamer).

This system is unlocked after clearing chapter 11-6.

Facilities

Vehicles replace Heavy Ordnance Corps in the Garage screen. HOC systems are all assembled in the Intelligence Center.

• Workstation: Used to select the vehicle on display.
• Mobile Armor Platform: Used to view and modify the displayed vehicle.
• Energy Generator: Continuously creates energy points to move vehicles during battle.
• Armor Range: Used to pass the tutorial for the displayed vehicles and make test runs.
• Components Storage: Lists owned components.
• Research Station: Shortcut to vehicles tech trees.

The Garage is open to visit by other players like the main Dorm. Players can "interact" with the vehicles in friend dorms, by taping the corresponding button and receiving 10 friendship points. After a successful visit, a text will be displayed which can be read after getting back to your garage and pressing "visit" button.

Systems

Each vehicle must be unlocked by completing a set of objectives (such as destroying a specific enemy) and completing a tutorial for the vehicle.

Up to ten configuration presets can be saved per vehicle.

Crew

Each vehicle requires a certain number of Dolls to work. The commanding Doll is also displayed on the vehicle. A mech might only need one pilot, but a tank might need a commander, a gunner, a loader and a driver.

Some crew positions are limited by unit type: some can only be filled by standard units, while others can be filled by assimilated units and Heavy Ordnance Corps.

The Dummy-Link number and level of the crew affects the stats bonuses they grant to the vehicle.

Components

Each vehicle has a number of component slots for Main Components and Universal Components. Like Equipment, components come in 3, 4 and 5-stars rarities, and can be upgraded (with other components or Component Processing Packages) or scrapped. They can be farmed in the hardest map of Gray Zone Exploration or obtained from Component Boxes.

Slots can accommodate heavy weapons, light weapons, defense components or function components. Some slots are unlocked by progressing in the vehicle's tech tree. Adding a component may add a stat to the vehicle's stats board, such as heavy/light firepower and penetration or night vision.

One of the component slots is the vehicle appearance. Vehicles can also receive new appearances by completing achievements or buying skins from the shop.

Main Components

Main Components provide an extra skill and set stats boosts. Each one also has three extra randomized “Entries” unlocked at levels 1, 3 and 10, which can be either another stat boost or passive skill.

Skills

Each vehicle has a set of base skills that can be upgraded or unlocked in the tech tree. More skills can be added by components.

In battle, some skills require aiming.

Tech tree

New component slots, skill upgrades and stats upgrades are unlocked by progressing in a vehicle's tech tree. Each node becomes available after accumulating proficiency and can then be unlocked with the four main resources.

Proficiency is only obtained by repeatedly using vehicles in battle.

Battle

Vehicles are deployed from heavy heliports and count toward the same deployment limit as HOCs.

Vehicles can engage in combat like normal echelons, or provide fire support from the map like HOCs do. They also expend ammo when acting and rations per turn like echelons and HOCs. They can retreat from heliports, but will forfeit all their ammo, rations and energy if they are not extracted from a heavy heliport.

Vehicles that are damaged in battle can be field-repaired at heliports (forfeiting the S-rank), but as long as they are not at 0 HP they will be fully repaired when the mission ends.

Energy

Vehicles spend energy to move instead of Action Points. A deployed vehicle carries a maximum amount of energy, which is replenished each turn from the backup energy from the base if there is any.

Vehicles energy is produced in real-time at the Generator facility, like Fairy Commands. It can also be purchased with the four main resources.

Note: Unlike every other player unit, vehicles cannot swap place with other units on the map since they use their own movement system.

Mobile Armor units

Currently, there are 2 obtainable Mobile Armor units. More may be added in the future.

Trivia

• As explained in promo materials, Griffin & Kryuger received permission from StateSec to use armored vehicles, which were provided by IOP.
• The vehicles system was teased in 2018, but it took five years before it was announced during Slow Shock's introduction stream, five months before client version 3.03.
