A Forward Operating Base that's built directly into a Bunker network. It provides Infrastructure for nearby connected Bunker and Trench segments
Construction
The Bunker Base is built by upgrading a tier 1 bunker with a Construction Vehicle for 300 Basic Materials. The bunker must be part of a large bunker with at least 5 additional bunker pieces (any tier, any upgrade). The bunker we're upgrading must also not be adjacent to a bunker garrison. For a bunker base tier 2 and 3, the prerequisites are the same as other Forward Bases (small Garrison Facility for T2, large for T3) except that for Tier 3 the Bunker Base must also have unlocked the "Concrete" infrastructure Upgrade. Tier 2 upgrade costs 100 bmats, Tier 3 costs 50 Concrete Materials.
Bunker Base Upgrades
Bunker base Upgrades contain the same upgrades as other forward bases but also have two additional upgrades trees ("Garrison" and "Command") to unlock bunker specific upgrades. Those bunker upgrades also require Infrastructure, which is provided by building Infrastructure Modifications in Bunkers. There are two types of Infrastructure: "Garrison" and "Command", one for each upgrade tree.
| Image | Name | Required Modifications | Description |
|---|---|---|---|
| "Base" Tree | |||
|
Provisional Garrison | Connects the base to nearby defensive structures (80m radius). Defensive structures will deactivate if player activity (set spawb) is too low (<10). | |
|
Small Garrison | Permanently connects the base to nearby defensive structures (80m radius).
Prevents nearby structure decay by consuming Garrison Supplies from the stockpile. Rate of consumption is 2 per hour per structure. Required to upgrade Base to Tier 2. | |
|
Large Garrison | Prevents nearby structure decay by consuming Garrison Supplies from the stockpile. Rate of consumption is 1 per hour per structure.
Required to upgrade Base to Tier 3. | |
| "Garrison" Tree | |||
|
Rifle Garrison | 4 | Allows connected bunkers to be upgraded into Rifle Garrisons. Requires 4 "Garrison" Modifications. |

Machine Gun Garrison | 8 | Allows connected bunkers to be upgraded into Machine Gun Garrisons. Requires 8 "Garrison" Modifications. |
|
AT Gun Garrison | 12 | Allows connected bunkers to be upgraded into AT Gun Garrisons. Requires 12 "Garrison" Modifications. |
|
Howitzer Garrison | 24 | Allows connected bunkers to be upgraded into Howitzer Garrisons. Requires 24 "Garrison" Modifications. |

| Deployment Point | 24 | Allows players to deploy to this forward base from the Home Region.
Requires 24 "Command" Modifications. | |
|
Storm Cannon | 40 | Allows construction of Storm Cannon. Requires 40 "Command" Modifications. |
Tips
- Once an upgrade that required Infrastructure Modifications is unlocked,removing the infrastructure modifications won't make you lose the upgrade or the ability to build the new bunker upgrade type.
