Yes but SPGs aren't sexy enough. Far hotter and more lucrative to whack a missile that costs 10 million dollars on a plane that costs half a billion so you can then launch at a two man sandbag pit on a hill somewhere. Did it miss? Oh well, no worries we'll fire another one tomorrow. If the plane hasn't broken down.

Yeah, the breech projects the gas going in the opposite direction, and usually self-propelled guns have longer barrels (the Msta-S is about 7.2m versus 5.2m on a D-20) which just means the gas is going to be projected that much farther from the crew.

The Russians (specifically the milita units back in the day) used more towed artillery, but they were often used in fortified positions.

The sound as well as the gases will be projected in the other direction because both the barrel and the breech are heavy pieces of steel.

Yeah, the length of the barrel and being armored compared helps a lot, ak lot of it is doctrine. That said, a fair amount of it is specifically the M777 howitzer.

The issue really isn't using the larger calibers that have been around since the First World War, but they tried to jam a medium howitzer into the weight class of basically a field gun. That means a much more aggressive muzzle break, no shield, a shorter barrel, frequent use of red bag charges, shorter lanyards, and usually no trench work, basically doing everything to promote TBIs as aggressively as possible in exchange for a lighter and more easily transportable gun.

It is a clear signal from the politicians to the brass to the average soldier that their livelihood is completely meaningless as tools of the empire.

Light steel is expensive, soldiers are cheap.

ever wonder if putin and xi are doing a very cool team up move to bait the usa into running into ukraine(-munitions -banderites), gaza(-Israel), yemen(-suez, -support), Iran (-fleet), Mexico (-fascists), nato collapse, correcting the greatest of America's geopolitical ills of the last century while giving a lesson on why the capitalist system is simply uncontrolled and bad for international diplomacy before it brings an economic failure and then people's revolutions up from the us, uk, ca, ger, fra, pol, ita, triggering the fall of capitalism and reestablishment of the soviet union, warsaw pact

kinda seems what all the pieces would fit together as in the long run, would be the ultimate flex, Putin said that thing about the ussr, would have a chinese harmony elegance to it, hm, if it occurs you will give me your kulaks

gradenko_2000 posted:

my understanding is that a lot of this has to do with the way artillery pieces are used and designed. It used to be that a "field gun" [high muzzle velocity, flat trajectory] and a "howitzer" [lower muzzle velocity, high-angle trajectory] were two different things.

a field gun would be 105mm artillery, and a howitzer would be 155mm howitzer, for example

the problem is that, at some point, NATO decided that all artillery should be 155m in order to use the same caliber shell all throughout, while also designed to be a gun-howitzer, or an artillery piece that can act as either a field gun or a howitzer

part of how a field gun manages to achieve its high muzzle velocity is that the calibre is smaller (105mm); a howitzer has a bigger shell (155mm), which means a heavier shell, but that's okay, since the muzzle velocity is expected to be less

but if you're trying to push a 155mm shell into the muzzle velocities demanded by field guns, you need to use much bigger (and more chemically dangerous?) powder charges to squeeze out every last bit of force

when you combine that with:

- artillery pieces also lack gun shields, because gun shields add weight, and you want the piece to be as light as possible for portability, when gun shields are important for protecting the gun crews from shock
- a muzzle brake design that projects more of the force back towards the crews (and all that extra force that has to be dissipated comes from, again, forcing 155mm artillery to act as a gun-howitzer)
- troops that aren't disciplined enough to dig proper firing positions for themselves

and you get artillerists with brain damage

somebody's going to have to dig up specifics, but as far as I know, Russia doesn't design artillery like this, and so doesn't run into quite the same problems (as much)

:hmmyes:

The other thing is political. They chose to "optimally man" the Marine artillery fighting ISIS because they did not want to make headlines about large formations of US troops being deployed. That meant that there was basically no crew rotation, and things got worse as more and more people dropped out ill.

You can’t have TBI if you just never test for it, which I guess was the plan until the year 2000 or so worldwide and is still the plan in a lot of places.

I've gone back and forth on this, and made that argument to the discharge board, but I've been around the guys who "had their bells rung" in Cyprus and Bosnia, or worked with their kids, and obviously the injuries were still there, just filtered through a different culture of injury and "treated" mostly with alcohol.

I would imagine if you go back and look at football and hockey players and boxers, you'll see the same thing. Leaving injuries completely untreated made them much worse, obviously, even if they were understood as personality quirks or whatever.

the standard American 155mm cannon that the m777 replaced, the m198, had basically the same tube and muzzle break, exact same lanyard, and same procedures around digging trenches. i think tbi stuff just was not a concern until recently, as modern tbi concern was kicked off by the iraq and Afghanistan occupation wave of IED injuries (and probably the wave of nfl player CTE awareness happening at the same time). I had no idea whatsoever that you could even get a tbi from firing artillery until I saw ff post about that here, and within a year or so of that the NYTimes articles on it came out.

It was also designed to be a lightweight gun, though weighed something like 40% more and did not often use red bags.

Yes, but it would be a hell of a lot easier to do with a purpose built anti-tank weapon like a tank cannon, ATGM, AT mine, maverick, hellfire, etc.

Just because you can doesn’t mean it’s optimal.

It's not an academic question, really. It has been done in combat on numerous occasions, but usually this is ignored as "well, that crew just sucked" and/or "they had a version that was deliberately made to be very lovely by the manufacturer, so it doesn't actually count, but please buy more of these versions."

The m198 had a barrel a good meter shorter as well. I am sure plenty of TBIs occurred with the m198, but the M777, with a shorter barrel/red bag charges is just going to make the situation much worse, especially the charges. It very likely isn't just because the army was now "looking for it" because there is clearly now less men able to work the guns.

US forces failed to stop attack after ‘confusion’ about drone: Report

US forces failed to identify the deadly drone attack near the borders of Jordan, Syria and Iraq because there was an American drone returning to the base at the same time of the incident, the Wall Street Journal reported, citing US officials.

The US drone’s return “led to some confusion” about the nature of the enemy drone, the officials said.

The Biden administration has blamed Iran-backed Iraqi groups for the attack, but a defence official told the Wall Street Journal that Washington has not found evidence that Tehran directed the attack.
