#5ThingsYouDontKnow The Answer Is: Two Japanese mortars - Type 10 and Type 89 - earned the nickname “Knee Mortar” among US troops. “The Japanese referred to the Type 89 as the Hachikyū-shiki jū-tekidantō, or Year 89 Grenade Discharger. They were issued at the platoon level to a single soldier who carried the tube strapped along the leg. This led quickly to the weapon being referred to as the ‘leg mortar.’ When US troops captured these weapons, a bad translation of this moniker led to the term ‘knee mortar’ and it has stuck. The curved T-shaped base of the Type 89 seemed to reinforce this belief. However, when US troops tried to test fire recycled knee mortars from the knee, bad things happened.”

For the record, modern (WW1 and on) mortars in fact are quite different from pre-WW1 mortars - specifically, in their intended use. Pre-WW1 mortars (or "bombards") were siege weapons as hinted in the first part of the video. Post-WW1 mortars are infantry support weapons/light artillery. That is quite a fundamental difference.

There is or was HEQ (quick) that burst on impact, and HED (delayed ) that would delay for about 1 sec then burst. The best ever fire missions for my mortar section was ones that included each type of fuse and rounds fired from the three tubes. WP, HEQ, HED, VT on a Time On Target mission.

You'll find even smoothbore mortars have an obturating ring, the ones on rifled mortars are designed somewhat differently so as to engage the rifling in the tube. But even smoothbores use them to ensure a good gas seal and eliminate 'barrel chatter' which can wreck accuracy.

@richardgreenleaf32598 жыл бұрын
Not sure that's true today. Certainly wasn't true when I was in school. From 1st grade through 3rd US history began with 1492 and Columbus. 1st through 2rd it went from Columbus straight to 1620 and the Pilgrims landing at Plymoth rock, then on to the American Revolution, then to the American Civil War. Beginning 3rd it went from the Pilgrims to the Salem Witchcraft Trials then to the French and Indian War before moving on to the American Revolution and continuing as it had. 4th grade broke things up a little, it went from Columbus to the Lost Colony to Jamestown then followed 3rd through the American Revolution before going on to Daniel Boone and the Cumberland Gap then moving on to the Civil War. 5th grade introduced a little on the settling of the colonies following Jamestown and the Pilgrims before following the 4th through Daniel Boone then introducing the War of 1812 and a brief bit on the antebellum period before hitting the American Civil War. 6th grade was the change, the year actually started with the Native Americans and the Bearing Land Bridge before moving on to Columbus and following 5th grade. 7th ignored all of that and touched a little on WWI and WWII but was mostly about government and the first half of the 20th century. 8th grade was back to 6th really. 9th grade there wasn't a history class really, officially it was government but it also included what should have been a fun archeology period (except some jerks kept going in at night and trashing our dig site so we had to set it up the grids again every day and never got anything done; according to the teacher it was supposed to have been a CCC fire prevention project site from the '30s). 10th grade we didn't have an actual history course, but we got our history lessons in English class and those were designed to tie in with English itself. So studying Greek and Roman myth we learned about the lives of folks in antiquity; reading "The Odyssey" we learned a little about Greek warfare; reading "Animal Farm" we had to learn about the early Soviet era. 11th grade had a history course but that was a bit of a joke. Plus I took two history electives that year, one for a quarter of the year which was more a generalized course and one which was more of an international history course that ran the full year. The core history course was technically American history, but I'd say I had more of my classmates asking me about the subject than they were getting from the teachers. And certainly when we got to the American Civil War about half the class was asking me about it. 12th grade was no American History, we studied Antiquity, the Middle Ages, the Renaissance, and WWII.

The most important thing to know is that they don't whistle like in the movies, they fly silently and just blow up. It's also important to know where they are firing from before you just go running wildly into the next area. Wait for the second round and move in the opposite direction if you cannot reach SAFE overhead cover in a 3-second rush, and don't go diving under a vehicle. And once you're location has been mortared once, you can be sure it will happen again and again.

Originally mortars were made of masonry mortar, however this proved to be too weak for sustained fire and were later replaced by metal tubes. 3. The US made M73 mortar can fire a round upto 278 miles. 4. The mortar was originally invented by the French and was first used in 1996. 5. Mortars have been trialled on the next generation of attack helicopters, however there have been problems with the round interfering with the rotors.

@Infinite_Jester7 жыл бұрын
I'm not sure I understand what you mean, but first you have a team measure the exact location and an exact bearing. Then you use an aiming circle and 'mirror' it with the sight of the mortar to get the exact bearing over to the mortar. Then you put a stick in the ground in the direction you're firing at and aim at the stick. You can also do it with a handheld aiming circle, which gives you an approximate bearing towards the place you're supposed to fire at. Again, you put a stick in the ground and then you aim at the stick with the sight. You might also do direct fire with mortars if you wish, but that's slightly different. Or you can just automate everything with computers.

@whomagoose68977 жыл бұрын
vtrmcs: All mortars and artillery are indirect fire weapons. The gun crews cannot see the target. Small poles are placed in front of the gun to "aim" at with the optics. Targets are hit by directing the gun some number of degrees, or mil-radians, away from those poles. Various amounts of charges are on each shell to get the desired distance. Also the angle of the canon, or tube, makes a difference. Forward observers watch the location of the impact and call to the gun crews to shift the gun to get on target. I spent 7 years as a mortar man working mostly on the now obsolete 4.2" mortar, called the 4-deuce. Charges were sheets of explosive material that was adjusted by 1/8th fractions. One sheet would be 4/8ths, two sheets sewn together would be 8/8ths, a bundle of 10 sheets would give 40 each 1/8th sections, or 5 charge amounts. A total of 42 charges were possible per 4.2" mortar shell. Wow, all that arithmetic I learned in school was useful after all.

nicknamed the Knee mortar, due to its baceplate looking like it was to be fired via the leg or knee, the one problem, it was not supposed to be fired that way, the plate was supposed to be jabbed into the ground, but in WWII, American soldiers got injured from misunderstanding the way to use it, injuries include dislocated legs and knees, fractured legs and knees, torn muscles. When used correctly, it was very affective, and the standard Japanese grenade could be adapted to be fired from the mortar, I know this stuff because I have watched docs on all things WWI and WWII, I'm a world war buff

I was an 81mm Mortar man in the Marines, and I loved the Wully P. rounds, thats "white phosphorus" for all you call of duty KZbinrs. Interesting fact about Wully P. rounds, they are an oxidizer and produce their own oxygen so the flame it produces or better yet heat can not be put out with water. It's a chemical burn that continues until it's burns itself out so if the Wully P. lands on you, you can't smother it with a tarp or extinguish it with water you need to remove that part of your flesh or just let it burn through. That is something I would like to use on a crowd of Antifa flag burning Millennials snowflakes.... but thats just in my world..... darn😒
@jekporkins60256 жыл бұрын
It's an allotrope of phosphorus, and it's the combining of the white phosphorus to oxygen molecules that in turn produce phosphorus pentoxide that causes the burning. The phosphorus doesn't just "create it's own oxygen" and cause itself to burn brighter, it's the chemical reaction to the air. It simply follows the laws of chemical equilibrium and conservation of mass.

"...used against tanks..." Also, I think the terminal guidance is more high tech than heat seeking, even though that sounds cool. I cant swear to it but idea is to penetrate top down centered on the turret for a catastrophic kill. A heat seeker would go for the engine/exhause which would only be a mobility kill. Interesting possibilities.

Knee mortar is a misnomer in more than one way. The Allies mistranslated the name 'Leg Mortar' it was never intended to be fired from the leg. It was made to be transported while strapped to the leg thus freeing the soldiers hands. And it wasn't really a mortar it was a grenade launcher.

Military's have had, for several hundred years, a required operational capability to engage threat infantry and thin-skinned targets with indirect fire. The "material solution" to this requirement was the mortar. Some would say field artillery can meet the requirement, and it can; however, relatively light-weight mortars (60mm and 81mm) are the infantry's "field artillery", capable of engaging the threat very effectively. The requirement has remained viable, i.e., true; the material solution has remained just as true: the mortar.

The answer to the trivia question is the "Knee Mortar" nicknamed this by American GI's due in part to how the base plate and bi-pod mounts were completely removed in favor of a lighter weight, single man portable, short mortar that could be deployed and fired from an infantryman's knee. It was an extremely effective tool that caused many US casualties during the island hopping campaigns in the pacific. Source believe it or not came from the popular video game Red Orchestra 2: Rising Storm. Where you could actually use the "Knee Mortars" in-game.

I would have to disagree with the second fact. While, yes, the weapon is still designed with a base plate, tube, a support system, and a targeting system; I would argue that these four things have vastly changed and evolved over the last century. The tubes are lighter, and designed to be light weight, cleanable, and enduring of any environment. The Bipods compared to back then are vastly more compact, lighter, and easier to handle. The base plate (even though the simplest piece) has adapted to be light, durable, and capable to fire 360* from any surfaces, for most infantry models. And the site. Mortar Sites have gone from "wing it", to iron site, to scopes capable of withstanding ordinance detonations. They are capable of being fired in any weather, and effective in night operations as well. Of course, these all sound like simple improvements, but if you look at the rifle, you could make the same point. The rifle has always had a stock, safety, trigger, bolt, chamber, magazine, forestock, sight, barrel, & Muzzle. Now with that in mind, would you say that the M4A1 is comparable to the M1 Grand? Both have all that was listed above, but one fires a different round, uses different materials, are different weights, and are vastly different when it comes to effectiveness in combat. The same can be said about the Mortar.
