It's been done, sort of. ISIS turned a couple into VBIEDs.
Which really isn't as scary as you'd think because they're huge, slow targets and the sturdy construction of the bed means it contains most of the explosive force within itself.
Those same reasons would make them kind of shit military vehicles. Big slow targets that don't really do anything helpful.
That is some Ork shit right there, all it's missing is checkers and red paint
I tried to find that clip of one of those dump trucks suicide bombing a base and this is all that showed up

Thanks youtube but not quite what i was looking for
Probably because related videos are ISIS propaganda and better off not available to everyone?
I mean i saw the clip on a documentary on youtube.
There's a pretty substantial difference between documenting ISIS and "Come join the caliphate, all the sex slaves and kuffar to slay you could ever possibly want. Enlist today and recieve a complimentary Kurdish concubine!"
It's amazing how many airframes are just chillin' in the desert. So many planes just... wasted.
The Tiger tanks weren't significantly larger than other heavy tanks, and they were already large targets back in the day. In modern times we can hit a tank from 10km away, from beyond visual range. There is no need for any complex coordination, it's rough location simply needs to be reported and an Apache can just find it and destroy it.
A huge tank doesn't do anything more than a regular tank does. A modern tank already has the power and sensors to destroy practically anything, it already destroys morale in that sense. Making it bigger only makes it easier for AT teams to spot and hit it, it massively reduces mobility and simply removes the ability to cross bridges. There are all things research groups all over the world worked on for the past century, and you're saying we should do the exact opposite because "it's scary". If anything, I'd be less demoralized if the tank that's trying to kill me can't physically reach me, and is a giant target.
Also the germans faced the conundrum of knowing that their production was significantly outnumbered. They couldn't have outproduced the others in lighter tanks anyway, going heavier wasn't the worst idea they had. A tank that lasts a little bit longer. Obviously the best choice would've been an early surrender and taking those resources to rebuild. But in the situation they were facing, it's understandable how they came to the conclusion they came to.
also the tiger is not the same as the isu-122, which was technically artillery.

Argentina has the Falklands.
Las malvinas son británicas
Unfortunately I no longer have the picture. But the Tiger 2 and Sherman where just about the same height, and had almost the same sized front profile.
someone correct me if I'm wrong but didn't the Falklands have a vote on what nation they wanted to be a part of and they voted to be part of Britain?
They did yes, I've recently come back from being posted there (ammo depot woop woop) and the locals are very happy to not be part of Argentina.

'Rush' is also a pretty decent movie, to be honest, definitely worth a watch.
It's a niche subject but if you like racing it's an easy 10/10.
That's when racing was a seriously dangerous thing too. Today you can have extremely serious wrecks that drivers waltz away from with a slight winding. But back in the day, everyone knew that ever year, several people standing there would not live to see the end of the season.
Turbine cars were extremely efficient, but only in a narrow power band, not to mention nearly impossible for the average owner to work on it without damaging something very sensitive. They also had long start up times, and huge amounts of hot exhaust to deal with, as well as a way to filter the insane amounts of air it sucks in without stifling the engine, they also can't really handle shock-loading that a car gives, like suddenly dumping or releasing the throttle. There just isn't any upside to a turbine car besides that it looks cool.
Jay Leno has a video on his Chrysler turbine car that really showcases all the problems they have.
Theres a reason that surface vehicles very, very rarely use turbines.

This was taken during sanation works on large landfill that is just 50meters away and workers were unprepared for the high winds. Trash was picked up next day by cleaning crews. This is what place looks like today https://www.index.hr/mobile/clanak.aspx?category=vijesti&id=2056659 and in future it will be an urban forest so #trashtag was already made last year when this video was taken.
It's funny how you cite Leno's video on it, while also claiming that they have an exhaust heat problem, even though leno specifically brings that up as a baseless myth about them. The Chrysler Turbines had a lower exhaust temperature than a regular car mate.
And regardless, i was specifically talking about racing.
Yes, I know, I was strapped for time while writing that and forgot about that. Chrysler did have an extremely good way of taking a lot of the heat out.
I think the best use case for turbine engines in automobiles is in a hybrid. Turbines are very efficient within their narrow powerband, and (IIRC) are generally lighter than a comparable reciprocating engine. So they would work very well at recharging a hybrid's batteries, then shutting off. That completely bypasses their drawbacks - horrible efficiency outside their powerband, and poor throttle response. Put it in a small hybrid car, and you could get a lot of range with a pretty small battery and auxiliary fuel tank, good for a cheap, efficient city car.
But it's also useful at the complete other end of the spectrum. I actually have some thoughts about a turbine/hybrid supercar. The core concept is that best way to show off your car isn't top speed, but acceleration (and let's be real, the point of a supercar is showing off). Electric cars already accelerate at nearly 1G, which is about the limit for a car with no downforce and without using exotic tire/road materials with a coefficient of friction >1. So it doesn't matter whether your car has 500 horsepower or 1,500 horsepower, you're still pulling away at about the same speed. Why spend a few million on a Bugatti or a Lamborghini when a Tesla is just as fast outside of the racetrack? Most of the rich assholes buying these types of cars don't take them to the track.
By using a turbine engine, you can either get crazy amounts of downforce even at a standing start (point the exhaust straight up), or you can just use it directly for acceleration (reaction engines aren't bound by that coefficient-of-friction limit). Or potentially both, if you do some one-axis thrust vectoring. For the same reasons as my first concept, you'd want it to be a hybrid - so you get the full-torque-at-0RPM of an electric motor, using a sort of turboshaft/turbofan mix to both charge the batteries (or maybe ultracapacitors?) and to give you lots of free downforce. That could bring your 0-60 time from the current ~2.5 seconds down to under a second. Of course, there are serious engineering challenges to face, not to mention some human ones... but I'm sure they could be solved for a car costing a few million dollars.
Yeah putting a non direct drive mechanical turbine on a car is absurd
Also while we're talking direct drive turbines, S2 time.

Predictably, it was useless at low speed and excellent at high speed. Able to start and pull 1000 tonnes over 100 mph as regular operation, but suffered from such pressure loss at low speed that the staybolts chronically failed due to the rapidly changing stresses of dropping from 300 psi to 80 psi when starting.
Bafflingly, this is the most ideal possible application for a booster, and even with that massive 6 wheeler trailing truck, no booster was ever fitted. But despite that, they did design and construct a prototype central turbine/gearbox assembly with transmission style planetary reduction and high speed cruising gear. Apparently going to the trouble and expense of building it, and yet they never installed it

Fucking bizzare.
Pennsy got real fuckin weird towards the end of the steam era and I love it. Would've been nice if they saved more of their one-offs as opposed to sending them all to the scrapyard but oh well.
Well we're getting 5550 at least.

Still, the Q1, Q2, S1, S2, J1, Franklin B1 and B2 K4's etc are lost to history. Utter tragedy.

" Photograph of a ravine in the Crimea known as the Valley of the Shadow of Death. The ravine is littered with cannonballs fired from the Russian
defences.
This iconic image of war was photographed by Fenton in April 1855. The ravine, named by British soldiers using a phrase from the 23rd Psalm,
shows the desolate landscape in which the battles of the Crimean War were fought.
The photograph was difficult to set up, and Fenton later wrote that ‘it was plain that the line of fire was upon the very spot I had chosen’. Fenton was forced to move 100 yards from his chosen spot to avoid the cannon fire, but ‘after this no more came near, though plenty passed on each side’."

Man that turbine is TINY. That thing must spin at insane rpms.
While we're on the topic of turbines and hybrids, this is exactly why Mazda is bringing the rotary back. The wankel engine is extremely good at high rpm running and is extremely compact while still making a lot of hp. They're coupling it to a motor/generator and putting in a hybrid.
Fenton and his assistants likely embellished the cannonball photograph. Another plate made from the same exact position shows the road free of cannonballs (this is a poor reproduction of it but you get the idea)

Some people disagree, but this type of visual deception is extremely common throughout the history of photography, and given the evidence, it hardly sounds implausible. Even if the circumstances in which he made the photograph weren't embellished (and they probably were), there was still some manipulation happening.
