Shaped charge torpedo scheme 
(2) Vol. 4 Page 4: The T-44 was not the first Soviet tank with planetary gear transmission: they originally still used friction clutches like the T-34. The T-54 was the first, and T-44s were later given them when upgraded to T-44M standard in the '60s.
(2) Let us go back to the beginning. In 8̶8̶2̶, R̶u̶r̶i̶k̶'s̶ s̶u̶c̶c̶e̶s̶s̶o̶r̶ P̶r̶i̶n̶c̶e̶ O̶l̶e̶g̶ 1954, Vladimir Chelomei's 'special design group' began work on the P-5 cruise missile. Previously, they worked on the 10Kh, the Soviet copy of the German Fi 103 aka V-1. 
(2) While these subs are not involved in the war, I find the class interesting and rather neglected. There are some good English articles about them (like @CovertShores), but generally not too much about technical details.
The Iraqi MiG-23MS experience 
KS-1 Komet and aircraft 'K' prototype 
Heh heh, I expected nothing less. 
(2/23) Named after Bucephalus, Alexander the Great's horse, the BTR-4 represents a break from the Soviet BTR-60/70/80 wheeled APC family. It is instead patterned on modern Western wheeled APCs such as the German TPz Fuchs. 
(2/21) To understand the BKP we must first go back to the T-34, which had a 4-speed gearbox (later improved 5-speed one) connected to an 'onboard/side friction clutch' (бортовой фрикцион), that also contained band brakes. This system was inherited from the Christie M1940 tank. 
(2/26) In 1986, the Soviets adopted the BTR-80 as a planned replacement for the BTR-70, based on combat experience in Afghanistan. Though outwardly similar to the BTR-70, the BTR-80 introduced some significant changes, most notably the side hatches, turret, and transmission. 
(2/25) While the M-13 ('Katyusha') and M-31 had proved successful during the war, the Soviets were impressed with German spin-stabilised rockets, particularly the 21 cm Nebelwerfer 42, which had superior accuracy and twice the range of the M-31. 
(2/23) To understand what the Tyulpan is and why it exists, according to Shirokorad, we must go back to April 1940. The Stavka was reflecting on the lessons given by the Finns that the Soviets had paid dearly for during the Winter War. Stalin, of course, was present. 
'Long-lived' (SU-100) 
(2/30) The Soviet airborne force, the VDV, have a long history of interest in SP guns. In the 1950s and 60s, they employed the ASU-57 and SU-85 SPGs. These were primarily anti-tank/direct fire weapons. 
(2/24) According to Sergey Gurov's 'MLRS Review', between 1969-1976, TulgosNIItochmash did design studies on an MRL for the Reserve of the Supreme High Command (RVGK). Development of the Smerch ('Whirlwind') project was formally ordered in 1976.
Wartime D-1 production was relatively small, at only 1,058 by the end of 1945. 
(2/40) In 1966, the Military-Industrial Commission (VPK) tasked KB-1 (today the 'Almaz' part of Almaz-Antey) under Aleksandr Raspletin with developing the next-generation S-300 air defense system. They had worked on all the PVO's previous SAM systems, from the S-25 to S-200. 
(2/30) 'Buk' ('birch', pronounced more like 'book', not 'buck') is the successor to the famous Kub/Kvadrat ('Cube'/'Square') SAM family, the standard army/division-level SAM of the Warsaw Pact in the 1970-80s.
