You are a NATO infantryman in Estonia.
Your Bradley has 300 km of fuel left. By the time it runs out, the petrol stations will have been emptied by looters.
The highways have been blanketed with fallout and are unsafe to use, normal fuel trucks are not well protected.
Every port in the Baltic has been nuked.
Railroads are blocked by rubble. No fuel trains.
Geiger counter says 600 mSv per hour outside the vehicle. You're not dismounting just yet.
You have a headache, you're not sure if it's the radiation.
Several members of your family are probably dead. You worry about those who survived.
You've been given the order to advance on what used to be St. Petersburg.
Your unit advances. Maybe a T-72 will spot you and put you out of your misery?
What would you do next in your country?
