It is also called a grenade launcher. It appeared during World War I as a way to throw hand grenades or grenades filled with smoke or tear gas farther than could be thrown by hand. Initially, a special launcher was attached to the muzzle of a rifle, but the 40mm M79 grenade launcher developed by the US Army during the Vietnam War was a lightweight, small, break-type single-shot gun, and the grenade used was a ball of wire wrapped around it with sawtooth cuts several feet long inside an aluminum shell, and packed with explosives. When the warhead hits the ground, it bounces off the ground and explodes at a height of about 1.5 meters. The wire ball breaks into about 300 pieces that fly at high speed, killing or wounding personnel within a 10-meter range. The maximum range is 400 meters. Riot-control tear gas guns are also a type of grenade gun. [Yoshio Kobashi] Source: Shogakukan Encyclopedia Nipponica About Encyclopedia Nipponica Information | Legend |
擲弾発射機ともいう。第一次世界大戦中、手榴弾(しゅりゅうだん)または発煙、催涙ガス剤などを充填(じゅうてん)した擲弾を人力手投げより遠方に投擲する手段として出現した。当初は小銃の銃口部に専用の発射機を取り付けたものであったが、ベトナム戦争中にアメリカ陸軍が開発した40ミリM79グレネードランチャーは、軽量小型の中折れ式単発銃で、使用する榴弾は、アルミの外殻の中に数フィートの鋸歯(きょし)状に切り込みの入ったワイヤーを巻き込んだ球があり、内部に炸薬(さくやく)が詰められている。弾頭は着地すると地表からバウンドして約1.5メートルの高さで炸裂する。ワイヤーの球体は約300個の破片となって高速飛散し、10メートル範囲の人員を殺傷する。最大射程は400メートル。暴徒鎮圧用の催涙ガス銃も一種の擲弾銃である。 [小橋良夫] 出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
