Question: Who led the military group that included Moscow Reserve Front and made it an effective fighting force?

full_context: Document 1: Moscow Reserve Front: The Moscow Reserve Front was a front of the Red Army during the Second World War. It was formed on 9 October 1941 on the basis of the Moscow defensive line in the Volokolamsk, Mozhaisky Maloyaroslavets Kaluga and fortified areas.
Document 2: The Blitz: British air doctrine, since the time of Chief of the Air Staff Hugh Trenchard in the early 1920s, had stressed offence was the best means of defence. British defensive strategy revolved around offensive action, what became known as the cult of the offensive. To prevent German formations from hitting targets in Britain, RAF's Bomber Command would destroy Luftwaffe aircraft on their own bases, aircraft in their factories and fuel reserves by attacking oil plants. This philosophy was impractical as Bomber Command lacked the technology and equipment and needed several years to develop it. This strategy retarded the development of fighter defences in the 1930s. Dowding agreed air defence would require some offensive action, and fighters could not defend Britain alone. Until September 1940, the RAF lacked specialist night-fighting aircraft and relied on anti-aircraft units which were poorly equipped and lacking in numbers.
Document 3: Oryol Front: The Oryol Front was very briefly a front of the Red Army during the Second World War. By a Stavka order of Mar. 24, 1943 it was set up on Mar. 27 by renaming the Kursk Front, while most of the forces of that Front were reassigned elsewhere. It was intended that the Front would contain 61st Army from Western Front and 3rd Army from Central Front, plus one additional army. The command staff remained as for Kursk Front, with Col. Gen. M.A. Reiter in command. Following yet another Stavka command in the early hours of Mar. 28 Oryol Front was renamed Bryansk Front.
Document 4: North Caucasian Front: The North Caucasian Front or North Caucasus Front was a major formation of the Red Army during the Second World War.
Document 5: Kursk Front: The Kursk Front was a front of the Red Army during the Second World War. It was set up on March 23, 1943, following a Stavka directive of March 19 by re-purposing the command cadre of Reserve Front to defend the westernmost sector of the Kursk Salient. It consisted of 38th Army, 60th Army, and 15th Air Army, with another field army to be assigned, probably either the 63rd or 66th. Col. Gen. M.A. Reiter was appointed to command, with Maj. Gen. I.Z. Susaikov as member of the military council and Lt. Gen. L.M. Sandalov as chief of staff. The new Front was very short lived. Another "Stavka" directive on March 24 transformed Kursk Front into the new Oryol Front, to be established by March 27. At the same time, 60th Army was transferred to Central Front, and 38th to Voronezh Front. Finally, on March 28, Oryol Front was ordered to be renamed as the new Bryansk Front.
Document 6: Kalinin Front: The Kalinin Front was a major formation of the Red Army active in the Eastern Front of World War II, named for the city of Kalinin. It was formally established by Stavka directive on 17 October 1941 and allocated three armies: 22nd, 29th Army and 30th. In May 1942, the Air Forces of the Kalinin Front were reorganised as the 3rd Air Army, comprising three fighter, two ground attack, and one bomber division.
Document 7: Modern history: The Russian Civil War was a multi-party war that occurred within the former Russian Empire after the Russian provisional government collapsed and the Soviets under the domination of the Bolshevik party assumed power, first in Petrograd (St. Petersburg) and then in other places. In the wake of the October Revolution, the old Russian Imperial Army had been demobilized; the volunteer-based Red Guard was the Bolsheviks' main military force, augmented by an armed military component of the Cheka, the Bolshevik state security apparatus. There was an instituted mandatory conscription of the rural peasantry into the Red Army. Opposition of rural Russians to Red Army conscription units was overcome by taking hostages and shooting them when necessary in order to force compliance. Former Tsarist officers were utilized as "military specialists" (voenspetsy), taking their families hostage in order to ensure loyalty. At the start of the war, three-fourths of the Red Army officer corps was composed of former Tsarist officers. By its end, 83% of all Red Army divisional and corps commanders were ex-Tsarist soldiers.
Document 8: The Blitz: In the 1920s and 1930s, air power theorists Giulio Douhet and Billy Mitchell espoused the idea that air forces could win wars by themselves, without a need for land and sea fighting. It was thought there was no defence against air attack, particularly at night. Enemy industry, their seats of government, factories and communications could be destroyed, effectively taking away their means to resist. It was also thought the bombing of residential centres would cause a collapse of civilian will, which might have led to the collapse of production and civil life. Democracies, where the populace was allowed to show overt disapproval of the ruling government, were thought particularly vulnerable. This thinking was prevalent in both the RAF and what was then known as the United States Army Air Corps (USAAC) between the two world wars. RAF Bomber Command's policy in particular would attempt to achieve victory through the destruction of civilian will, communications and industry.
Document 9: Stalingrad Front: The Stalingrad Front was a front, a military unit encompassing several armies, of the Soviet Union's Red Army during the Second World War. The name indicated the primary geographical region in which the Front first fought, based on the city of Stalingrad on the Volga River.
Document 10: Kliment Voroshilov tank: The Kliment Voroshilov (KV) tanks, a series of Soviet heavy tanks named after the Soviet defence commissar and politician Kliment Voroshilov, operated with the Red Army during World War II. The KV tanks were known for their heavy armour protection during the early stages of the war, especially during the first year of the German invasion of the Soviet Union. In certain situations, even a single KV-1 or KV-2 supported by infantry could halt large German formations. The German Wehrmacht at that time rarely deployed its tanks against KVs, as their own armament was too poor to deal with the ""Russischer Koloss"" – "Russian Colossus".
Document 11: Leningrad Strategic Defensive: Leningrad Strategic Defensive Operation is the term in Soviet historiography for the defensive operations of the Red Army and Soviet Navy during World War II from 10 July to 30 September 1941. The following operations are considered as part of the strategic operation:
Document 12: Anti-aircraft warfare: The most extreme case was the Soviet Union, and this model may still be followed in some countries: it was a separate service, on a par with the navy or ground force. In the Soviet Union this was called Voyska PVO, and had both fighter aircraft and ground-based systems. This was divided into two arms, PVO Strany, the Strategic Air defence Service responsible for Air Defence of the Homeland, created in 1941 and becoming an independent service in 1954, and PVO SV, Air Defence of the Ground Forces. Subsequently these became part of the air force and ground forces respectively
Document 13: Battle of Warsaw (1920): The battle of Warsaw was fought from August 12–25, 1920 as Red Army forces commanded by Mikhail Tukhachevsky approached the Polish capital of Warsaw and the nearby Modlin Fortress. On August 16, Polish forces commanded by Józef Piłsudski counterattacked from the south, disrupting the enemy's offensive, forcing the Russian forces into a disorganized withdrawal eastward and behind the Neman River. Estimated Russian losses were 10,000 killed, 500 missing, 30,000 wounded, and 66,000 taken prisoner, compared with Polish losses of some 4,500 killed, 10,000 missing, and 22,000 wounded.
Document 14: Northwestern Front: The Northwestern Front (Russian: "Северо-Западный фронт") was a military formation of the Red Army during the Winter War and World War II. It was operational with the 7th and 13th Armies during the Winter War. It was re-created on 22 June 1941, the first day of the Soviet-German War on the basis of the Baltic Special Military District. On 22 June the Front consisted of the 8th, 11th, and 27th Armies, as well as the 5th Airborne Corps and the headquarters of the 65th Rifle Corps.
Document 15: Red Army: In the late 1920s and throughout the 1930s, Soviet military theoreticians led by Marshal Mikhail Tukhachevsky developed the deep operations doctrine, a direct consequence of their Polish - Soviet War and Russian Civil War experiences. To achieve victory, deep operations envisage simultaneous corps - and army - size unit maneuvers of simultaneous parallel attacks throughout the depth of the enemy's ground forces, inducing catastrophic defensive failure. The deep battle doctrine relies upon aviation and armor advances in the hope that maneuver warfare offers quick, efficient, and decisive victory. Marshal Tukhachevsky said that aerial warfare must be ``employed against targets beyond the range of infantry, artillery, and other arms. For maximum tactical effect aircraft should be employed en masse, concentrated in time and space, against targets of the highest tactical importance. ''
