Q: Information: - This article is about a Japanese World War II infantry mortar . For the main battle tank , see Type 10 . The Type 10 grenade discharger ( Juu - nen - shiki tekidant ) was a Japanese smoothbore , muzzle loaded weapon used during the Second World War . It first entered service in 1921 . The Type 10 has a range of 175 meters , greater than other grenade dischargers of that time . It had a range control device at the base of the barrel in the form of a graduated thimble by which a gas port at the base of the tube could be varied in size . For shorter ranges , part of the propellant gases escape to the side . Due to a translation error , the Type 10 was called the '' knee mortar '' by the Americans . The manual for the mortar instructed the troops to carry the mortar on the upper thigh , with the base plate attached to the belt and the barrel running down the thigh . It must be understood that it was not strapped or secured directly to the thigh , but hung from the belt . It was also carried strapped to the backpack . American troops on Guadalcanal became aware of the name '' knee mortar '' and thought the light design allowed it to be fired with the base plate resting on the thigh . If the Type 10 were fired in this manner , it would result in serious injury due to recoil . However , once a few troops injured themselves , the mistranslation was discovered and further experimentation discouraged . Contemporary US intelligence thought that the weapon was primarily used to discharge flares , the heavier Type 89 Grenade Discharger being used to fire explosive rounds instead . - A grenade launcher is a weapon that fires a specially-designed large-caliber projectile, often with an explosive, smoke or gas warhead. Today, the term generally refers to a class of dedicated firearms firing unitary grenade cartridges. The most common type are man-portable, shoulder-fired weapons issued to individuals, although larger crew-served launchers are issued at higher levels of organisation by military forces. - Japan ("Nippon" or "Nihon" ; formally "" or "Nihon-koku", means "State of Japan") is a sovereign island nation in Eastern Asia. Located in the Pacific Ocean, It is lying off the eastern coast of the Asia Mainland (east of China, Korea, Russia) and stretching from the Sea of Okhotsk in the north to the East China Sea and near Taiwan in the southwest. - World WarII (often abbreviated to WWII or WW2), also known as the Second World War, was a global war that lasted from 1939 to 1945, although related conflicts began earlier. It involved the vast majority of the world's nationsincluding all of the great powerseventually forming two opposing military alliances: the Allies and the Axis. It was the most widespread war in history, and directly involved more than 100 million people from over 30 countries. In a state of "total war", the major participants threw their entire economic, industrial, and scientific capabilities behind the war effort, erasing the distinction between civilian and military resources. Marked by mass deaths of civilians, including the Holocaust (in which approximately 11 million people were killed) and the strategic bombing of industrial and population centres (in which approximately one million were killed, and which included the atomic bombings of Hiroshima and Nagasaki), it resulted in an estimated 50 million to 85 million fatalities. These made World WarII the deadliest conflict in human history. - The , inaccurately and colloquially known as a knee mortar by Allied forces, is a Japanese grenade launcher or light mortar that was widely used in the Pacific Ocean theatre of World War II.
