In the checked live build, your direct strategic choice is the matchup: select two countries and press Fight. The simulation then runs the armies. Its source says victory occurs only after the enemy capital falls and remains occupied for the required internal period.
Quick answer: the matchup is your main input
- Click one country, then a second country on the map.
- Press Fight when both selection slots are filled.
- Use 1x, 3x, or 5x to change simulation speed; End stops the run.
- The visible interface does not expose tactical unit commands after the battle starts.
The actual victory rule
The live app's source explicitly rejects force-advantage and territory-only shortcuts. A side wins after the opposing capital falls and the invader holds it long enough for the internal occupation condition. The exact duration is not published in the visible interface.
What can influence the simulation
The app displays manpower, factories, rifles, missiles, and stance. Its source also derives field strength and reserves from an internal military-data model. That makes country selection relevant, but it does not provide a guaranteed matchup table.
Unknown and no-guarantee boundary
There is no documented player build, upgrade path, or combat command to force a win in the checked build. A favored country can still be a simulation outcome, not a player skill proof. This guide does not invent odds or best-country rankings.
