The scenario we ran
Russia, Belarus attack Ukraine in autumn, mobilization full / partial, the United States stays out, nuclear weapons disabled, 365-day limit. Everything else is the engine's realistic default.
How the model played it out
Result: Defender holds after 365 simulated days (duration limit reached). Aggregate personnel losses within the model: 115,805 for Russia + Belarus and 68,974 for Ukraine.
The war moved through initial strike from day 1, then rapid mobilization from day 3, then attrition phase from day 8, then stalemate from day 21, then end state from day 365.
Turning points:
- The engine detected no turning points in this run.
