Yes, destroy train lines, oil, gas, and petrol stations, loot and burn police stations, fortify highway overpasses so Russia has to bomb their own infrastructure or lose large amounts of men. Burn factories connected to rusdian war effort. All while infiltrating hundreds of saboteurs into the general population to instigate smoking accidents all across the federation.
