OBSERVATION STATION

Provincial early-warning infrastructure built around long-range detection. Active Radar Range expands from 75 at Level 1 to 200 at Level 4, while the maximum tier adds explicit Stealth Detection. Construction requires Combat Outpost Level 1 in a rural province.

Observation Station Conditions

01
Rural Province
The structure must be deployed in a rural province.
02
Combat Outpost Level 1
The province must contain Combat Outpost Level 1.
03
Level 1
Level 1 requires no tech-tree investment.
04
Mobile Radar Branch
Higher tiers update automatically through the Mobile Radar research branch.

Mobile Radar Cross-Sync

Doctrine changes only the supplied research day and radar-platform reference. Observation Station radar range, sight, combat values, HP, costs and roles remain shared in this source.

Radar Progression

Radar Expansion
Active Radar Range expands through 75, 120, 175 and 200 across Levels 1–4.
Research Automation
Level 1 requires no technology investment. Higher tiers update automatically with Mobile Radar L1, L2 and L3.
Maximum Tier
Level 4 combines 200 Active Radar Range, 0.5 / 0.5 Combat ATK / DEF, 10 HP and explicit Stealth Detection.
Source Conflict // Interceptor Wording
The supplied Tactical Blueprint calls the Observation Station a provincial interceptor shield and says it is specialized against aircraft and helicopters. That wording does not match the rest of the same page, which defines this structure through Active Radar Range, Visual Sight, surveillance roles, Mobile Radar research and Stealth Detection. The explicit level matrix is therefore used for the displayed mechanics while the conflicting overview wording is preserved here rather than silently rewritten.
Data Integrity // Level 4 Visual Sight Not Supplied
Visual Sight is explicitly 32.5–37.5 at Levels 1, 2 and 3. The Level 4 matrix replaces that field with Special Capability: Stealth Detection and does not supply a Visual Sight value. Level 4 therefore displays — instead of carrying the previous value forward.
Source Note // Mobile Radar vs Radar Tech Labels
The level cards label the higher-tier requirements as Mobile Radar L1 / L2 / L3, while the doctrine cross-sync table labels those same tier gates Radar Tech L1 / L2 / L3. Both source labels are retained in their original contexts rather than normalized into one terminology.
Doctrine Separation // Research Timing Only
The doctrine matrix supplies different research days and radar platform references for Eastern, European and Western doctrines. It does not provide doctrine-specific Observation Station radar, combat, sight, HP, role, deployment or upkeep values. The selector therefore changes only the supported timing and platform reference.
