Naked Bear posted:For our discussion, the conservation of momentum when each gun is fired is more relevant: as the projectile has a momentum of some magnitude and direction, so too does the gun have an equal and opposite momentum (y'know, recoil). If each gun was mounted on a truck and the weight of each gun was also similar (Wikipedia claims they are similar enough *cough*), then the chief differences between them would simply be the angle of their momentum relative to the truck (and thus, the angle at which they apply an impulse to the truck) and what that impulse to the truck would be like (i.e. how they each manage the recoil). The 120mm gun's momentum would be roughly horizontal to the ground while the 155mm gun would have both significant horizontal and significant vertical components to its momentum (i.e. it would be at an angle). The impulse that each would impart on the truck I don't know, because I don't exactly have lots of technical information about either gun and high-speed footage of each recoiling, so let's just say "gently caress it" and claim that they're roughly comparable and either one would wreck a trailer in short order. If you're considering momentum, though, you can't just consider the projectile, because much of the momentum is that carried by the propellant gases, and the 155mm gun is using a much larger propellant charge. But yes, I think the takeaway is the same: truck trailers ain't designed for that poo poo.

Interesting attack plan: Drive right up to a tank and start shooting with small arms. Doesn't work too well. https://www.liveleak.com/ll_embed?f=cb39ad713605

250lbs of HE doesn't really care whether it's contained in a steel bomb case or a pickup truck when it goes off. Any difference in sound isn't something someone could perceive. Different kinds of HE have different blast characteristics. Two quantities of merit are called brisance and heave. The former is directly related to detonation pressure, which in turn determines the strength of the shockwave. The second is the capability of the explosion to do work. You can think of brisance as the capability of the bomb to break things into pieces, and heave as how far it throws them. Military explosives are generally higher brisance because they're in a steel case that is intended to fragment into shrapnel and not just burst open on one side. Military explosives are also more energetic than non-military, because military explosives operate under tight constraints. If you want a bigger car bomb, steal a bigger car. If you're mining, drill a bigger hole and pour in more ANFO. But you can't make an artillery barrel or bomb case arbitrarily wide. What this means is that a 500lb. GP bomb which is about 250lbs of steel bomb case and 250lbs of HMX will be more energetic than 250lbs of Semtex packed into the frame of a car, both because it's going to turn the 250lbs of steel bomb case into flying lawnmower blades, and because 250lbs of HMW will release considerably more energy than 250lbs of Semtex. But this is all engineering differences, stuff that maybe you could determine after the fact by forensic examination of the scene of the explosion. If either of them goes off right next to you there's no loving way you'd be able to tell the difference based on your own senses. Obviously the sound of an aerial bomb or artillery shell falling on your head is going to sound different than someone driving an old Yugo up to your checkpoint, but I don't think that's what you mean.

Phil Moscowitz posted:I was just wondering in the context of Syria for example, as we've seen investigations into whether an explosion in a hospital or other civilian building was caused by an airstrike or by a bomb, how reliable are eyewitness accounts of what they see/hear/feel as far as the explosion is concerned. Eyewitness accounts about *anything* aren't reliable.

45 ACP CURES NAZIS posted:Mortars aren't accurate in the sniper rifle sense, but a good gun crew, FO, and plotters will be getting good effect on target in under four rounds Why the overcompensation? If the first round is 100m to the left why doesn't the observer just compensate and adjust 100m to the right?

Yeah, that makes perfect sense. I understand bracketing for a larger error but if the first round was 100 meters off I'd expect just "right 100 (or whatever in mils) and fire for effect."

chitoryu12 posted:It won't damage the power of the round by a meaningful amount, but it does deflect the round up or down depending on whether you're shooting in or out. Windshields are hard and take a good amount of energy to penetrate, and a hollowpointed round like carried by the police isn't going to make it through unscathed.. The much ballyhooed Teflon-coated cop-killer bullet, the KTW round, was a round invented by cops specifically to be able to reliably penetrate car windshields. https://www.theboxotruth.com/the-buick-o-truth-2-windshields-outsidein/ Also I hope that guy was wearing earpro. aphid_licker posted:My reaction got a bit more understanding when I read the bit about the guys having killed someone hours ago but I would seriously prefer my police to not just loving spray rounds out of their moving vehicles ObMeToo: Me too.

I just watched the movie while on a transatlantic flight. There's no such line. The book has a whole bit about the Red October and other soviet subs having sensitive gravitometers installed and using that data to compare against the data from their gravitometric surveys of the seafloor to precisely fix their positions underwater, but the movie dispenses with all that and glosses over it, substituting "hyperaccurate surveys of the underwater canyons."

PM: Don't tell me about the press — I know exactly who reads the papers. The Daily Mirror is read by people who think they run the country. The Guardian is read by people who think they ought to run the country. The Times is read by people who actually do run the country. The Daily Mail is read by the wives of the people who run the country. The Financial Times is read by people who own the country. The Morning Star is read by people who think the country ought to be run by another country, and the Daily Telegraph is read by people who think it is. Sir Humphrey: Prime Minister, what about the people who read the Sun? Bernard Woolley: Sun readers don't care who runs the country, as long as she's got big tits.

Motorola 68000 posted:I saw a video on about this on youtube a loooong time ago. I think the most successful knee mortars were fielded by the Japanese during WWII if I'm not mistaken. It was, but the point is that "knee mortar" is a misnomer. GIs who tried to use a captured knee mortar by bracing it on their legs wound up with a broken leg. Or that's the story, anyway, I'm not sure how common it actually was. Sounds like a UL.

Poles find a leftover Tallboy in the middle of a shipping channel (it was dropped during a raid on the German heavy cruiser Lutzow, which sank in shallow water and kept being used as a static battery) and try to defuse it. Or rather, they try to ignite the explosive fill in such a way as to have it deflagrate rather than detonate. Here's how that went: https://twitter.com/aneta_l/status/1316042287902871552?s=20

Scope posted:What's the cost of one of those Iron Dome guided interceptor missiles vs. the cost of an unguided rocket. Iron Dome only engages if the inbound is going to hit something important. The correct question is what’s the cost of one of the interceptors vs. the value of what the unguided rocket is going to blow up.
