Soviet T-34s and training, veterans of the Chinese civil war — versus — Constabulary force without tanks, anti-tank weapons or combat aircraft.

What actually happened

The model's verdict is emphatic, and June–August 1950 proved it: Seoul fell in three days and the South was compressed into the Pusan perimeter within weeks. What no force table shows is the outside world — the UN intervention, Inchon landing and Chinese counter-intervention turned a three-month rout into a three-year stalemate ending almost exactly on the original border.
