What Research Unlocks
Units — half the checklist — and all eight doctrines.
UNITS: TECH + BUILDING
New unit types are the primary purpose of research, and it works alongside a building requirement rather than replacing it — every producible unit needs both the right completed tech(s) and the rightbuilding type/level present at the city. Finishing the research only satisfies half that checklist; nothing queues automatically, and a unit can still be unbuildable if the building isn't there.
THE EIGHT DOCTRINES
| DOCTRINE | UNLOCKED BY |
|---|---|
| ESCORT | Air-to-Air Missiles, T1.0 |
| CAP (COMBAT AIR PATROL) | Air-to-Air Missiles, T1.3 |
| WILD WEASEL | Air-to-Ground Missiles, T1.6 |
| TANK HUNTER | Anti-Tank Missiles, T1.6 |
| SHOCK AND AWE | Air-to-Ground Missiles, T2.0 |
| DEEP STRIKE | Cruise Missiles, T2.0 |
| MARITIME STRIKE | Naval Missiles, T2.0 |
| LAYERED DEFENSE | Surface-to-Air Missiles T2.0 and Air-to-Air Missiles T1.0 — the only doctrine needing two techs |
A doctrine becomes available the instant its required research completes — no separate unlock step, no building requirement. It's selectable and usable on eligible units immediately.
