Not sure why you'd use drones rather than just tiny remote controlled model airplanes.

What's the difference?

Multicopters are mechanically simpler and capable of hovering. Kind of a win-win. The drawback is that the fixed wing plane may have longer endurance with a battery of a given size than a multicopter would, but if your communication range is limited for some reason, then this may not be relevant.

I'd like to mess with them at home, but not at "the necessary volumes" to go through a foot of steel as in the video. You know those little bang snaps you throw at the ground and they make a popping sound? For DIY, ideally, I'd do things in that kind of volume. I'd probably need a smidgen more, but I wouldn't want to do more than e.g. make a pinhole in 29 gauge sheet metal. What I'd really love to make -- but I don't…

Small rocket engines can be made with some pyrodex, dowels, and cardboard tubes. Most high explosives involve nitric acid of decent concentration. It’s hard to make them in quantities small enough to be actually not dangerous, especially since many of the compounds will react with all sorts of normal everyday substances (like aluminum, copper, etc) to form even more unstable compounds. Some of them can even explode o…

Published in '43, so won't have some of the newer exotics, but comprehensive regardless. Sometimes hard to find, but Amazon has new hardcovers for $20. Don't blow your hands off.

> The Iraq War was a protracted armed conflict in Iraq from 2003 to 2011 that began with the *invasion of Iraq by the United States–led coalition*... Whilst I agree that the preceding comments are off topic with their own inflammatory agenda's I do think it's important in generally acknowledging the war was caused by a US led invasion based on lies. Disclaimer: I fought there and lost people there, and after, but tha…

No, I don't think many people did. But as a soldier you don't have a choice, you go where you are told.

Just following orders ? https://en.wikipedia.org/wiki/Superior_orders

Have you ever been in the military? I'm guessing not.

Glib though your answer is it hasn't been that long since people were shot for not following orders. And at 17-18 years old you're unlikely to question much you're told to do, especially after training/indoctrination. Most of the time I had no idea what I was actually doing or why, but when you end up having to fight for your life and those of your muckers you do what you must trying to survive. Trails come if you survive.

Fireworks level explosives are fun and doable at the garage level. I don't think you can do real "shaped charge perpetrators" but you can do some really fun things like explosive welding and such.

I think that's a good starting point. Any good references? I'm looking up the one already given in thread. I have a lot of experience with medical biohazards, high voltages (>2kV), welding, dangerous tools, handling dangerous liquids (HF and similar), etc. I've never hurt myself. That's enough background to know not to do things before I know how to do them safely.

In the US/Iraq war such contraptions were commonly referred to as EFPs (explosively formed penetrators). My platoon was once hit by a four-array EFP that was hung behind a cement wall (US forces would often line streets with barricades like this) so we couldn't see it. It went through the concrete wall, the humvee, and took some legs with it. Brutal things they were. We avoided prolonged truck excursions, but I remem…

Devious. The assassination of Alfred Herrhausen is I think the textbook example of this technique: https://en.m.wikipedia.org/wiki/Alfred_Herrhausen

> When Herrhausen's motorcade approached the attack site, the lookout waited for the lead car to pass by the bike, then radioed to the terrorist in the bushes who quickly activated the beam. Herrhausen's vehicle broke the beam which triggered the electronic detonator in the bomb. The front of Herrhausen's car broke the beam at the precise moment the back right seat, where Herrhausen was sitting, was directly across from the bomb. The force of the explosion was aimed at where Herrhausen was sitting. The bomb was placed on a child's bike to match the height of the back right door of the armored vehicle. To develop this attack, the terrorists had to compute the speed of the car, the length of the car, and the height of the back right door. As his car passed the bike, at 8:34 a.m., the bike exploded and some 22 pounds of TNT propelled schrapnel through the right rear door, forcing a piece of the armored door into Herrhausen, pushing him across the back seat into the left door. The force of the explo- sion, which took place 3 feet away from the right rear door of Herrhausen's vehicle, threw the 2.8 ton armored vehicle across the street, approximately 82 feet. The driver was slightly injured.

Interesting, thanks for sharing. A few things stand out (spoilers of course) - the Chairman of Deutsche Bank had an armoured convoy with two vehicles with bodyguards. It makes sense seeing that someone was trying to kill him, but outside of that context it seems a lot. Most European politicians, including heads of state and government, have less today. Second, he bled to death. I wonder what circumstances led to this…

The explosive device contained approximately 22 pounds of TNT, and detonated 3 feet away from the right rear passenger door.

yes i have but it was mandatory conscription . My point still stands though .

I guess it's always a risk analysis if you will end up in the winning or losing team .

I amuse myself by thinking that Sidney Alford (the expert in the video, who by the way appears to have passed away last year) looked like, and was, the modern Grand Maester, conjuring up magical (but yes, destructive and terrible) explosives for the use by kingdoms against each other. He should've been given a cameo part in Game of Thrones... I got onto the topic years ago when watching the Dambusters. Related to thi…

does that make the rainbow six siege breach charge somewhat accurate? In that, if it doesn't knock the whole wall down like the first part of the video, there would be a door-shaped hole. https://rainbowsix.fandom.com/wiki/Breach_Charge/Siege

Yes, "wall breaching charge"

Question: Is there a way to play with these things at home? Any pointers to DIY stuff?

You could probably make what you need but it's both unsafe & will most likely get you put on a list depending where you live. There are jobs where you can get hands-on training and experience if you really want it.
