Bagaimanapun, Joes akan rusak mereka! Lagi pula, Sersan Mayor pernah ditembak dengan optik ketika ia adalah seorang prajurit muda, sehingga tidak akan tentaranya. Lalu kami pergi ke perang. Tiba-tiba, banyak tentara menemukan diri mereka dengan sepotong asing peralatan duduk di atas senapan dan karaben. Bintara harus cepat melatih prajurit mereka pada penggunaan yang tepat mereka. Masalahnya, banyak bintara tidak pernah dilatih. Aku mulai mendengar beberapa hal yang sangat aneh sebagai bintara berjuang membantu pasukan mereka. "Kau harus membuat permen lolipop" "Apa CCO berdiri untuk, sersan?" "Ini berarti dekat pertempuran optik. Itulah mengapa tidak akurat lebih dari 100 meter. " "Titik menggantikan pemandangan belakang. Pasang titik pada posting pemand...

Big Ivan, The Tsar Bomba (“King of Bombs”)

Gambar
The World's Largest Nuclear Weapon   The device offically designated RDS-220, known to its designers as Big Ivan , and nicknamed in the west Tsar Bomba (and referred to as the Big Bomb by Sakharov in his Memoirs [Sakharov 1990] ) was the largest nuclear weapon ever constructed or detonated. This three stage weapon was actually a 100 megaton bomb design, but the uranium fusion stage tamper of the tertiary (and possibly the secondary) stage(s) was replaced by one(s) made of lead. This reduced the yield by 50% by eliminating the fast fissioning of the uranium tamper by the fusion neutrons, and eliminated 97% of the fallout (1.5 megatons of fission, instead of about 51.5 Mt), yet still proved the full yield design. The result was the "cleanest" weapon ever tested with 97% of the energy coming from fusion reactions. The effect of this bomb at full yield on global fallout would have been tremendous. It would have increased the world's total fission fallout sinc...
