I'm sorry, but when somebody tells you "we will ship you 7000 miles away to fight in a different continent" and you accept, you share at least some part of the responsibility. There would be no wars without greedy politicians, but there would be no wars without soldiers too.

I hear where you are coming from, but the discussion is out of place, reeks of privilege and lacks perspective.

I've seen and heard many things being said, but calling the Iraqi point of view ‘privileged’ is truly new.

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.

For anyone else who was intrigued and wanted to see more, I found the full documentary here: https://www.youtube.com/watch?v=k1_sMaMcLG8

Presumably this is of dubious legality, but I can't find any official way to view it online in the U.S., or any recorded media form you can buy.

We call them : The Iraq War ( https://en.wikipedia.org/wiki/Iraq_War ) and the Russo-Ukrainian War ( https://en.wikipedia.org/wiki/Russo-Ukrainian_War ) This is a discussion about a special kind of explosive and a first hand story on how it is used in a conflict. Leave politics aside.

> 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…

Shaped charges are also used to create the holes (perfs) in wellbores prior to fracking. The shaped charges blast through 1/2 inch of steel pipe and then a foot or two of rock. Sand and water are then pumped through the holes to prop open the rock and allow oil, gas, and water to flow out with less resistance.

there was a defcon talk where they tested multiple methods for rapid hard drive erasure, in the event of a raid on a data center. a bomb range they visited happened to have a few of these leftover and https://youtu.be/-bpX8YvNg6Y?t=2135

And you have just described the AeroEnvironment Switchblade 600 drone. According to Drive they haven't actually been deployed in Ukraine yet but they are on the list apparently. The smaller 300 has been deployed apparently but it doesn't carry a shaped charge, instead it carries an antipersonnel charge. More of a flying hand grenade kind of deal.

It's all fun and games until you realize your country has no deniability about being at war with Russia.

It is weird right? And yet it isn't either. Selling weapons to people so they can vanquish their enemies has been a time honored tradition. If we were less invested in which side won, I wouldn't be surprised to see companies selling to both sides, because business is business right?

There are "rules" (and by rules I mean what is interpreted as "participating" vs "supporting" in a conflict that have been established and enforced for well over a thousand years. And supplying weapons has been firmly established in the 'supporting' category not the 'participating' category.

This conflict is illustrating a lot of things that haven't been seen since the cold war, which is an opportunity to learn new things about how the world works if you haven't seen it before.

The next interesting step happens when this conflict settles out, what does it look like.

This type of explosive is very stable... nothing like nitroglycerin ...

The explosive is stable (small cubes of most plastic explosive can even be lit on fire and act as fuel). But there is still danger in correctly handling/connecting the detonator. I'm not sure, but I thing the acceleration charge might be a less stable type as well (obviously they aren't going to give us step by step instructions).

>obviously they aren't going to give us step by step instructions

It’s thoroughly explained in the manuals freely available at US Army web site.

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…

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.

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

Don't even think about it. Just watch youtube and be happy. I know a guy who got stuck with a felony conviction for making his own fireworks. He can no longer work anything other than menial jobs.

> (obviously they aren't going to give us step by step instructions). nitrocellulose is very simple to make and detonate... and is also very stable.... I don't see why we need secrets... I played with that stuff when I was a teenager

When I was in college in Toronto in 1961 there was a surplus store. All manner of WW2 radios etc. I looked at one pile and it was about 15 rolls of primacord. This was a long 5/16 hollow tube of vinyl filled with pure TNT. It resembled rope = rope pile/ $3/roll of 100 feet. 2/$5. I knew what it was, so bought it all. it being worth $25-30/roll/ I was an Engineering stoont and Russia had just set of their Czar bomba.…
