Fast Building Checks

Use these as a quick mental model before you dig into tier-by-tier costs and unlocks.

Economy

Start with Arms Industry and Local Industry for stronger income, then use Recruiting Office when faster mobilization matters to your tempo.

Access

Air Base, Naval Base, and Bunker-type infrastructure usually matter less for raw economy and more for mobility, reach, and survivability.

Unlocks

Check the unlock column first when planning research paths. A building tier that opens the next unit often beats a small economic gain.

Recruiting Office

Recruiting Office improves unit mobilization speed. The table below shows the tier bonus from the game data plus the effective time reduction it implies.

Example: a +25% speed bonus means mobilization runs at 125% speed, which works out to roughly 20% less time.
