This is an idea to blow a hole in an underground pipeline without digging a hole and not spending too much time at the site. Build a large enough bomb to reach to pipeline with it’s explosion. Bring an extra vehicle (disposible) with you to the site. Preferably a truck. Load the truck with sandbags. At the site, remove some sandbags and place on top of the bomb but not enough prevent the truck from driving over it. Drive the truck over the bomb and leave it. Let the air out of the tires. The idea is that the weight placed on top of the bomb helps to direct the blast downward ensuring it destroys the target. It is the same principle used by construction crews when using dynamite. They have massive steel mats they place over the explosives. Finding the location of pipelines is relatively easy. Here in Massachusetts you simple call 1-800-dig-safe
General
Destroying the roof of a building is one idea. The roofs of most buildings are weaker than the surrounding walls, and it will do more damage. It would be even better if was raining or snowing. If you can't make a bomb and get it on the roof of a building, get a high powered rifle or pistol and shoot holes in the roof.
Tactics For A Popular Uprising
Fake News Stories
Aleister Crowley was one of the first to try to use the media for his own purposes by getting stories printed that leave historical clues. Two examples would be the Loch Ness Monster as The Scottish Enlightenment and his traveling to Egypt where he was 'given' his religion Thelema. Unfortunately 100 years of trying this has produced nothing so I expose it here. I think part of the reason nothing ever happens is people are frozen in place by all the surveillance. The first idea to fight back is to use that tactic on a large scale like computer hackers use 'denial of service' attacks. Flood local radio and TV stations with reports that revolution has broken out to try to get real revolution going. If an ordinary fire breaks out, report it as revolution. Help things along with fireworks.
Communications and Electric Grid
Here is an idea to shut off power to a large number of telephone poles before cutting up the wires. Locate a substation. A substation is where the very high voltage of the high tension wires is stepped down for use locally. Substations can usually be found very near high tension wires. Cut down the nearest telephone pole in a direction away from the substation itself pulling the wire with it. This disconnects the wire without touching anything. Do this to enough substations close together and the wires might be dead. It takes time for the transformers on the poles to discharge.
There is a transformer on every few poles all across the country. They can be quite expensive. Shooting a couple holes in them would destroy it. This could also be used on microwave/cell phone towers.
Almost every telephone pole has a grounding rod next to it. I know that coax cable must be continuisly grounded as it goes. There must be a wire extending from the top of the pole to the rod at the base. Cutting this wire may disrupt service.
The trucks used by electric company's (cherry pickers, etc) are very expensive. When they are using them they leave the engines running because it powers the equipment attached to it. A pellet gun could be used from a somewhat safe distance to puncture the radiator. Five or ten minutes after the radiator is empty, the engine will overheat and sieze making the truck useless. This could also be done to police and fire trucks.
Pour acid on the bolts that hold down the towers that hold high tension wires. Or come up with some way to weaken the structure. The next big wind will blow it over.
Have you ever been to a sporting event and seen them shooting t-shirts into the crowd? Those can be powerful and easily made. Instead of shooting t-shirts rig a piece of non-insulated wire with a couple weights attached. The weights could be hard wooden balls or something. Make the wire long enough to span a couple of high tension lines. Use it to short out high tension lines. The closer you are to a power plant, the more likely you would do damage to the plant itself. This is reasonably silent, which would help.
Communications are necessary to fight back, as are other utilities, but they need to be managed by the people at the bottom. Nationalized if you will. The United States will never go that far back in time, unless global anarchy is the only solution. They all need to be located and probably destroyed and then rebuilt. Back in the 1990's there was a company called Global Crossing. It was part of the dot com boom and bust that happened. They strung fiber optic cable to all continents despite the fact we were only using 4 or 5 percent of the fiber optic capacity that had already been built. The company went bankrupt, the government made a half-assed attempt to go after the people who were responsible but they eventually walked away with millions. That network is a very powerful tool and it would be wise to know who has it now and where it is being managed from. The actual cables have to come ashore somewhere. The facility that accepts it should be destroyed and enough of the cable so it can't reach the shore again.
Transportation
Create traffic jams in inner city areas by stopping some vehicles and destoying them. Or get some cheap cars get on a highway at rush hour, get next to each other to block the highway, stop and light them on fire. Doing this in areas like downtown Manhattan would create a nightmare traffic jam.
Most places where railroad tracks cross a paved street the rails are at the same height as the pavement. This is done for the cars to cross the rails. The idea is to destroy a small section of the rail where it is the same level as the pavement. It could be easier to hide the damage from people who inspect the tracks. Fill it in with sand or something. The crossings are accessible to anyone and wouldn't attract too much attention. Whatever they use to bring down buildings might eat away enough to work. (World Trade Center) Thermite is a mixture of chemicals that can melt iron and steel. If placed on a railroad track it could damage the rail enough to cause a train to derail. Almost every railroad cross's a public road where the tracks are accessible. I say this because in Massachusetts they are off limits. This would help to stop world trade. Recipes for Thermite can be found in 'The Anarchist Cookbook 2000'. A free pdf is on the right of this page.
Here in New England we have a terrible problem with potholes. In the fall water seeps into cracks in the pavement and then freezes when the weather gets below zero. When this happens it expands and pushes the asphalt apart causing the pothole when spring arrives. It makes a real mess. The idea is to do this intentionally so as to destroy a road in rural areas. A place to fight back from is necessary and this would help to build that. Destroying hotels and vacation homes would make it hard for people who aren't commited to revolution from entering that area.
Another idea to stop world trade would be to shut down harbor's. Grab a couple of ships just outside the harbor and sink them in the shipping lane.
Police and Personel
Spray utensils (knives, forks spoons) cups and plates with swamp water or any stagnant water. It can be teeming with bacteria.
