Go out and build obstacles in the streets! Start with any bridge you can find (they should have been destroyed). Block them with cars, trucks, concrete, wood, trash, anything! Then block any spot in the city where there are tall buildings on each side. Already tight areas.

If it is a street you still need to use. Build a S pattern obstacle that still slows a vehicle down. Think police check point (which you could set up if you wanted to catch saboteurs before military reach your location)

Yes, use your molotov cocktails. Think about where you will stand to throw (then run). Dropping from windows above vehicles most ideal. Vehicles without weapons on top the most vulnerable, but if it is armor, choose where to hit.
