— In-game description
A Bunker is a player-built structure partly-dug into the ground with a Shovel. It can be upgraded for more Health and better Resistance and transformed with various Modifications. It can be connected to other Bunkers and Trenches.
A Tier 1 Bunker is built with a Shovel. It can be connected to other Bunkers by their sides and to Trenches by their ends or their center (hold Shift to deactivate auto-snapping). It can't be built on Beaches, paved areas, ice, roads, or steep slopes.
Tier 2
A Tier 2 Bunker is built by upgrading a Tier 1 Bunker with a Hammer and 75 Basic Materials.
Tier 3
A Tier 3 Bunker is built by upgrading a Tier 2 Bunker with a Hammer and 15 Concrete Materials. However it needs to be connected (by trench or bunker) to a Bunker Base with the Concrete Structures upgrade.
The concrete must dry off for 24 hours before a Structure Upgrade modification can be added. The duration increases during Snow Storms and Rain Storms depending on their intensity (up to double with highest intensity).
While very sturdy when dry, it is vulnerable while still wet. The vulnerability depends on how wet the concrete is and functions as a damage multiplier. Wet concrete that's just been placed has a x10 damage multiplier compared to dry concrete. After 8 hours the damage multiplier is roughly x3, and x2 after 12 hours.
Structural Integrity
A Bunker greatly decreases the Structural Integrity of its Bunker Network: greatly if Tier 1, slightly if Tier 2, very slightly if Tier 3
Bunker Network
If you directly join two bunkers together, the wall between them disappears and they become one single Bunker Network with shared health. If one of the parts gets destroyed, they all get destroyed.
Modifications
Modifications can be added to a Bunker with a Hammer in "Upgrade" mode (switch with F), press E to open the upgrade menu.
Small Modifications
Adding a Small Modification makes your character perform a short construction animation after which the modification appears. The materials will automatically be taken from your inventory. Use Mouse Wheel to select the orientation and position of the Small Modification when relevant. They can be removed by pressing Right Click on their icon option in the upgrade menu instead of Left Click.
An Infrastructure Modification can be installed inside a Tier 2 or Tier 3 Bunker if it is connected to a Bunker Base by Trenches or Bunkers (up to a maximum range of 40 pieces). It can be installed even if a Structure Upgrade is already present, as long as that upgrade is on the top of the Bunker (like a Rifle Garrison) rather than inside the Bunker (Engine Room). It costs 50 Basic Materials to install and 25 Basic Materials to remove, no matter the type. Each bunker piece can only have one and it must rest against a wall (e.g. not in the middle of a 3x3 bunker network). Use Mouse Wheel to select the desired position during placement.
Infrastructure modifications are either Garrison Infrastructure or Command Infrastructure. They contribute to the Infrastructure requirement to unlock the Base Upgrades at all the Bunker Bases connected to them by Trenches and Bunkers, up to a maximum range of 40 pieces.
Infrastructure modifications also contribute different bonuses to all the connected bunkers to them (40-piece range as well). A bunker loses the bonus if its connection to the relevant Infrastructure Modification is severed.
Some kinds of infrastructure modifications only become available after a certain amount of infrastructure modifications of the same infrastructure type have already been built in the network of connected bunkers and trenches.
Garrison Infrastructures
They are needed to unlock Infantry Garrisons (4), AT Gun Garrison (12), and Howitzer Garrison (24).

Structure Upgrades
A Bunker can be modified into various specialised structures. Only one Structure Upgrade can be installed and it cannot be removed once built. It deletes all Small Modifications and Infrastructure Modifications that are in conflict with it (e.g. sandbags & ladder add-ons removed when placing a bunker garrison, or infrastructure modification removed when placing an engine room).
Most Structure Upgrades require that the Bunker is connected by trenches or bunkers to a Bunker Base with certain base upgrades unlocked. The direct chain of bunkers and trenches linking them must have 40 or fewer pieces (including the Bunker itself and the Bunker Base).
The upgrade's impact on its Bunker Network's Structural Integrity is mentioned in the description. "High - Medium" means the integrity is currently "High" (0.75-1) and will become "Medium" (0.5-0.75) if the upgrade is added.
A radio bunker that provides intel to friendly units about the surrounding area. Reinforced with wood, it can withstand more punishment than a standard radio tower, and therefore is capable of increased effectiveness.
Support Bunkers
Only on Tier 2 and Tier 3 bunkers.
Cannot be adjacent to another garrison Upgrade, even diagonally.
A high-tech listening post designed to intercept and decode enemy transmissions. The intelligence Center can target distant locations and will continue to decipher sensitive transmissions over a sustained period.
Advanced Bunkers
Only on Tier 3 bunkers.
Cannot be adjacent to another garrison Upgrade, even diagonally.
Requires a 3 by 3 bunker complex.
A high-tech weather module built on solid foundations within a bunker network. These stations help operators predict weather patterns. Multiple Weather Station modules may be chained together to make more accurate predictions, allowing armies to prepare for the worst conditions.
Advanced Bunkers
Only on Tier 3 bunkers.
Cannot be adjacent to another garrison Upgrade, even diagonally.
Requires a 3 by 3 bunker complex.
Reservation
The original builder can reserve it for a Squad for 52 hours in the upgrade menu to prevent non-members from modifying it, upgrading it, or attaching structures to it. The reservation can be refreshed by any squad member. If the reservation expires, the structure can never be reserved again.
Demolition
The original builder, and squad members if reserved, can instantly demolish it if it was built less than 3 hours ago. The materials used in the construction and upgrades are refunded and dropped under the player. If part of a Bunker Network, it must be fully repaired. The demolition doesn't affect the other bunkers inside that bunker network.
Reconstruction
When destroyed, it leaves behind a husk that can be either destroyed or rebuilt. Reconstruction uses the same tool and materials as the construction of its current tier (e.g. shoveling for Tier 1, Hammer and 75 bmats for Tier 2). It cannot be rebuilt if an enemy base is less than 25m away. The Structure Upgrade modification on it is lost (except Bunker Base) and will have to be reinstalled at normal cost after the reconstruction. The reconstruction restores all small modifications and infrastructure modifications but only if the bunker had no Structure Upgrade modification installed.
Unlike trench husks, bunker husks cannot be filled in with a shovel.

Use
Defensive Position
It offers great cover and good firing positions for infantry, especially with some small modifications installed. Bunker interior can protect infantry against Artillery. It also slowly warms up infantry in it during Snow Storms.
Bunkers are neutral structures by default if no Structure Upgrade modification is installed on them. An enemy can add or remove small modifications and Infrastructure Modifications from your bunker unless it is connected via Trench/Bunker to a friendly Bunker Base or if it is in the same Bunker Network as a friendly Bunker with a Structure Upgrade modification installed (e.g. Rifle Garrison).
When destroyed, the husk it leaves can still be used by soldiers to hide inside it by crouching but it offers worse cover than a normal bunker or trench. All vehicles can drive over bunker husks. The husk also does not protect infantry from Snow Storms.
Spreading Base Upgrades
The Base Upgrades unlocked by a Bunker Base spread through and apply to all connected Trenches and Bunkers, up to a maximum range of 40 pieces. Bunker husks also spread Base upgrades.
Resistance
At Tier 1, it is immune to small arms and fragmentation grenades, but not to 12.7mm machine gun fire or heavier explosives. Tier 2 makes it immune to 12.7mm. Tier 3 increases its resistance to heavy explosives except Demolition explosives.
When it's destroyed, every infantry in it dies. Even vehicles that touch the bunker might be instantly destroyed.
The destroyed Bunker husk has the same health and resistance as it had when alive but its decay is faster and cannot be prevented.
Tips
Upgrading T1 Rifle Garrison to T2, T3 Rifle Garrison is cheaper than build T2, T3 bunker first and upgrading to Rifle Garrison. Upgrading T1 Rifle Garrison to T2 costs 75 Basic Materials and T2 Rifle Garrison to T3 costs 30 Concrete Materials like normal bunker does.
