Military Research is one of four technology disciplines available at the Library. It increases the 
Population Limit and unlocks new units and military technologies.
Benefits[]
Like all Library research, Military research has a total of 7 levels to research. Each level researched...
- ...increases the Population Limit by +25, up to a maximum of 200.
- ...unlocks all military units of the same Age.
- ...reduces production cost for units of previous Ages by 5% per level ahead.
- ...reduces upgrade cost for units of previous Ages by 10% per level ahead.
Researching Military technology also unlocks all military structures (except Docks) as well as Forts technologies.
Note that research cost also depends on the current level[note 1] of 
Science research as well as any cost modifiers from nation powers and rare resources.

Rare resources[]
- Furs reduce
Military research cost by 25%. However, this does not work with the "red" future technology Missile Shield.
Nation powers[]
- The Aztec Power of Sacrifice and the Roman Power of Caesar: Start with Military 1 (The Art of War) already researched (unless playing a Nomad or City Center Only game).
- The Bantu Power of Migration: Receive +50 to their Population Limit per Military research. They also do not require Military research to unlock new units. However, unit and upgrade costs are increased by 10% per age behind in Military research.
- The Greek Power of Philosophy: Receive a general 10% discount on all Library research cost (except for Knowledge) and research technologies 100% faster.
- The Turk Power of Siege: Military research are 33% cheaper.
Trivia[]
- As mentioned in the trivia section of the Library page, researches have alternate titles depending on the starting and ending ages. For Military Research, they can be seen here.
Notes[]
- ↑ As mentioned in the Notes section of the Science Research page, the actual effect on the cost of all researches is more complex than the in-game tooltip indicates. You can see more details here and in the description of the AGE parameter in Techrules.xml.
