## View Structure Health

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**  upgrade for T2, **Large Garrison**  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.

**Recommended unlock order (Assuming you are solo player)**

1. Provisional AI (5-30mins)
2. Small Garrison AI (13 hours-1day)
3. Infantry Garrisons (RG & MGG) (5-30 mins)
4. Large Garrison AI (2 days +- half)
5. ATG (1 day)
6. T1 Obs Bunkers (4-12hrs)
7. T2 concrete (1 day)
8. T4 HG (2 days +- half)
9. T3 Deployment point (3 days)

The time it takes to unlock an upgrade vary depending on how many people have their spawn assigned to the base, the base's supplies, and whether the base is in a region that started in your faction's control at war start or not.

Once an upgrade for a specific bunker garrison is unlocked, bunkers that are connected to the bunker base via trenches or bunkers can be modified to become that specific bunker garrison type (if they don't already have a modification installed). The maximum range of the bunker tech is a chain of 40 connected bunker/trench pieces (distance to Bunker Base is irrelevant), i.e. the tech doesn't reach a bunker if the shortest connection to the bunker base is a chain of more than 40 trench/bunkers. Once a particular bunker has been modified into a bunker garrison it won't lose its modification if its connection with the bunker base is severed, it can even still have its tier upgraded. However, to upgrade a bunker to T3, it must be connected to a core that has unlocked concrete; if the connection had previously been severed, it must be reconnected.

## 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.
* Bunkers and Trenches connected to a bunker base (via trenches or bunker) stop being neutral structures and become owned by the bunker base's faction. Their add-ons can no longer be removed by the opposing faction.
* Bunker Bases are immune to friendly fire, unlike Forward Bases.
