I'd heard many times about the barrel wear and just accepted it as a fact and never actually wondered why, so thanks for asking that:

https://en.wikipedia.org/wiki/San_Shiki_(anti-aircraft_shell)

quote:

Even though the 3 Shiki tsûjôdan shells comprised 40% of the total main ammunition load of the Yamato-class battleships by 1944, they were rarely used in combat against enemy aircraft. The blast of the main guns turned out to disrupt the fire of the smaller antiaircraft guns. In addition the copper drive bands of the rounds were poorly machined and constant firing was damaging the gun rifling; indeed, one of the shells may have exploded early and disabled one of Musashi's guns during the Battle of the Sibuyan Sea.
... which leads to:
https://en.wikipedia.org/wiki/Japanese_battleship_Musashi

quote:

During this attack, Musashi fired sanshikidan anti-aircraft shells from her main armament; one shell detonated in the middle gun of Turret No. 1, possibly because of a bomb fragment in the barrel, and wrecked the turret's elevating machinery.

Wouldn't bomb fragments in the barrel make any fired round gently caress up the gun?

Reminds me of how the British had a significantly higher casualty rate than the Americans in their Shermans, because British tankers wore soft berets instead of helmets

This sounds apocryphal. Any difference would surely be swamped by the differences in the fighting they faced on their sectors of the front.

EDIT: My googling doesn't show up anything, anyway.

It's late and I need to go to bed but I remember the number being somewhere just under 1 KIA per Sherman knocked out in US service, and higher for the British Army.
I think Chieftain mentioned it in one of his videos, or it might have been one of the tankfest lectures. I can't remember if they had a figure for Soviet Shermans.

Regardless, not having a helmet is going to mean you are more likely to suffer injuries (be they major or minor) from hitting your head during violent manoeuvres, such as losing a track to a mine, or rolling into a ditch, or any of the other exciting things that can happen to a tracked vehicle.

It depends on the motivation and whether the people leading the revolution think that killing the people in charge is not only okay, but necessary. The American Revolution took place an ocean away from the main government they were fighting against, but the Continental Congress didn't start demanding the execution of loyalists. George Washington and Thomas Jefferson weren't saying to behead the governors who didn't join their side. Seizures of property and exile, yes, but not murder. When the Crown acquiesced to independence, the war was over. British soldiers went home, 80+ million loyalists remained and became Americans. Relations even remained positive enough that both nations engaged in trade and diplomatic relations immediately after the war ended, though the War of 1812 was a rocky moment.

With the French Revolution, there was a sense that the royals and aristocrats were directly and personally responsible for everything and people like Robespierre hyped the people up into wanting heads on pikes. He glorified the idea of terrorizing the populace to keep the peace after a revolution, and the bloody revolution had created factions that were equally willing to kill for power; when you make your revolution about storming the palace and killing the people in charge, it becomes hard to stick around as a peaceful-minded group and maintain any semblance of authority. Now you have a government where all the different people vying for power are the kind who are fine with killing for it, and killing becomes the order of the day.

That's because the American revolutionary leaders didn't want to dismantle the unjust system, they wanted to take the place of those at the top of it.

They were fans of democracy and freedom in the classical sense, i.e. for rich slave-owners

It was a war over representative government. England had pretty strong democratic traditions (for the time) where men with property could get a say in how they were governed, and the colonies themselves had a number of self-governed institutions, so that's what gave them the idea that there was a reason to not just accept things when England levied some extra taxes and tried cracking down on non-mercantilist trade. It might seem like a smaller thing in the grand scheme of things, but that's what mattered to them at the time.
It was a war to exchange being ruled by British landowners for being ruled by American-based landowners

The main issue with shaped charges is that they have a very focused explosion, so you will get absolutely hosed up if you're standing in front of one when it goes off, but just being slightly off to the side can leave you mostly unharmed, while a HE or frag round would ruin everyone in the blast radius. You can see a bunch of examples of this from Syrian civil war videos where people were sniping each other on hilltops with ATGMs (do not watch these).

It might not have all the fragmentation of the purpose-built anti-personnel round, but the HEAT RPG warhead still has four times as much explosive in it as an M67 hand grenade. Sure the HEAT jet might miss you but you're still copping that blast and fragments of the casing.

Timed fuzes were used to make the shell explode at a certain time after firing, hopefully at the same height as an enemy aircraft. The Allies had sufficiently advanced electronics in the latter half of the war to introduce radar proximity fuzes that would explode near an object without having to have a time selected before firing.

Artillery firing at ground targets also used time shells in the hope of making them explode just before impact for maximum effect (shrapnel spreading out instead of being directed upwards out of a hole in the ground), this was much easier to achieve with proximity fuzes.


On a related note, how much of a hazard was falling shrapnel from AA shells and cartridge cases or bullets from aircraft to civilians beneath who weren't being directly targeted?

Every element heavier than iron (element twenty‐six) has an unstable nucleus, though lead at eighty‐two and most of the things in‐between have isotopes so long‐lived they’re never been observed to decay and likely never will. The light elements are vulnerable to proton decay, but that will happen long after the universe is in heat death and there is no energy around to run a player or a mind to appreciate it.

Are you sure about that, and that you're not mixing it up with iron being the end-point of (non-supernova) stellar nucleosynthesis?

For an example of a design flaw that doesn't translate into gameplay, look at the Panther tank. It was a 45-tonne tank with a drivetrain designed for a 30-tonne tank, which meant it was ridiculously vulnerable to breaking down. It broke if the tank made a sharp turn on rough terrain, it broke if the driver switched gears while going downhill, it broke if the tank went 100 kilometres without being checked by a mechanic. But in a video game that doesn't simulate that, the Panther's heavy armour and gun make it an objectively superior tank even though its weight was the thing making it unreliable .

And even that nice gun is directly impacted by another flaw that very few games include: the gunner is looking at the world through a drinking straw as he has no 1x sight, and the commander can't override the turret traverse and so has to call out instructions to the gunner until the gunner can see the target in his sights.

I broke a bone (fifth metatarsal) in my foot a few years ago. After two weeks in a protective splint it wasn't setting straight (the broken ends were angled downwards), and so a surgeon aligned the two pieces and put a pin through them, which was removed six weeks later.

Instead of having a limp for the rest of my life, I walk normally.

I've also had impacted wisdom teeth pulled (one of which needed to be broken up in place to be extracted), which was all done with local anaesthesia and sterile instruments.

Is there an advantage to wetting sails?

Edit, book from 1874:

The Yacht Sailor. A Treatise on Practical Yachtsmanship, Cruising and Racing posted:

Some one suggests "wetting the sails." On this point I would say a few words to you. No doubt wetting swells the threads of the canvas, which then offer a closer surface to the action of the wind ; but if the sails are new they do not so much require it, and the jumping about of the men will do more harm than good. Another disadvantage may arise from their not being wetted evenly, which, in the hurry and excitement of the moment, the chances are they will not be ;
Is this correct?

Edit 2: a person on Quora says that's not the reason:

quote:

I’m old enough to have raced dinghies with canvas sails!

The wetting of canvas sails to decrease porosity was a common belief, but probably not the reason it appears to work.

You only wet sails when it was ghosting conditions and there was a little chop or swell, the sails would flop about and you might just drift around, spinning in circles. What wetting canvas sails did was stiffen the sail due to swelling of the fibers.and that would reduce the flopping. You can get a feel for it if you have an canvas hat or bucket with no sizing and wet it. Voila! Your hat/bucket now holds its shape, salt water does a particularly good job. If you could keep the hull steady, wetted sails would hold their shape enough to provide some drive.
They've said it on the internet, so it's probably true

Solid, I think.

I know there was a lot of excitement in the middle of the 19th century about explosive shells but I don't know the reason(s) why they weren't in wide use before that time.

The latter half of the 19th century was a weird and wonderful time for weapons design. My favourite is the brief popularity of compressed-air-powered dynamite guns from the 1880s until the availability of more stable explosives (that could withstand the shock of firing from a conventional gun) rendered them obsolete.
