One of the most effective tactics I saw in ukraine was building walls of tires, filling them with dirt, gravel, rocks, or anything, and lighting some of them on fire to create smoke. Tires are everywhere in a city. a vehicle without tires is barrier and concealment. And tires filled with dirt are cover, ‘berms’, that stop bullets. Smoke provides concealment, and men in concealment can throw molotovs. There was no way to get into the center except on foot. tanker trucks, bridges, tires, smoke. siege. It is very difficult for a military or police to fire on citizens and have a government survive. Ever policeman or soldier is signing his own warrant. Every commander betting he won’t be hung. It is easy to talk about it. It is very difficult to do it. Conversely, It is very easy to fire on military and police who attack civilian positions of resistance in a siege.the military uses concrete and heavy machines. the citizenry uses tires, dirt, gasoline, glass, and a lot of arm and leg work. the central problem is not this strategy it is as simple as supplying the citizens with porta-potty’s food, bottles, and gasoline. Then the gradual taking, looting, offices so that the bureaucracy cannot go to work and organize, and the politicians gradually lose power, and the police and firemen start to stay home. In ukraine they were stalking police back to their homes. Eventually, as long as the pressure of continuous expansion of citizen held territory expands, and more and more institutions are inoperable, and banks close, and businesses close, and traffic stops, and gasoline runes out, the state must choose to become what they claim they are not, or to acquiesce as they have every single time in the past. Therefore the problem a revolution faces is simply making moral demands on behalf of the people, so that it is possible for the government to give in.
