Question: Johannes "Macky" Steinhoff, was a German general, NATO official and Luftwaffe fighter ace during World War II, and became one of the principal officials tasked with building the German Air Force during the Cold War, the aerial warfare branch of the Bundeswehr, the armed forces of which country?
Context: The Afghan Air Force (AAF; Pashto: دافغانستان هوائی ځواک ; Dari: قوای هوائی افغانستان), formerly the "Afghan National Army Air Corps", is the aerial warfare branch of the Afghan Armed Forces.  It is divided into three wings, with the 1st Wing at Kabul, the 2nd Wing at Kandahar and the 3rd Wing south at Shindand in western Afghanistan.  Lt. Gen. Mohammad Dawran serves as Chief of Staff of the Afghan Air Force and Major General Abdul Wahab Wardak is the Afghan Air Force Commander.  The command center of the Afghan Air Force is located at Kabul International Airport and the Shindand Air Base in Herat Province serves as the main training area. Werner Baake (1 November 1918 – 15 July 1964) was a German "Luftwaffe" night fighter ace and recipient of the Knight's Cross of the Iron Cross during World War II.  The Knight's Cross of the Iron Cross was awarded to recognize extreme battlefield bravery or successful military leadership.  Baake claimed 41 nocturnal aerial victories in 195 combat missions.  Baake was the 36th most successful night fighter ace of World War II, and of aerial warfare.  Baake's total surpassed that of all Allied night fighter pilots. Hans Beißwenger (8 November 1916 – 6 March 1943) was a German Luftwaffe fighter ace and recipient of the Knight's Cross of the Iron Cross with Oak Leaves during World War II.  A flying ace or fighter ace is a military aviator credited with shooting down five or more enemy aircraft during aerial combat.  In 500 combat missions, Beißwenger was credited with 152 victories, making him the 34th highest-scoring Luftwaffe fighter pilot of World War II.  He was "ace-in-a-day" twice, shooting down five aircraft on a single day.  He claimed all but one of his victories over the Eastern Front.  He was reported missing in action in March 1943. Friedrich-Erich Obleser (21 February 1923 – 5 June 2004) was a German general in the Bundeswehr.  During World War II, he served as a fighter pilot in the Luftwaffe.  A fighter ace, Obleser was credited with 120 aerial victories and was a recipient of the Knight's Cross of the Iron Cross of Nazi Germany.  For his post-war service in the German Air Force, he received the Grand Cross with Star of the Order of Merit of the Federal Republic of Germany. Wilhelm Crinius (2 December 1920 – 26 April 1997) was a Luftwaffe fighter ace during World War II.  A flying ace or fighter ace is a military aviator credited with shooting down five or more enemy aircraft during aerial combat.  Crinius is credited with 114 aerial victories claimed in approximately 400 combat missions.  He recorded 100 victories over the Eastern Front.  Of his 14 victories claimed over the Western Front, one was a four-engined bomber.  On 23 September 1942, Crinius became the only German fighter pilot to be awarded the Knight's Cross of the Iron Cross ("Ritterkreuz des Eisernen Kreuzes") and the Knight's Cross of the Iron Cross with Oak Leaves ("Ritterkreuz des Eisernen Kreuzes mit Eichenlaub") simultaneously. Johannes "Macky" Steinhoff (15 September 1913 – 21 February 1994) was a German general, NATO official and Luftwaffe fighter ace during World War II.  He joined the West German government's Rearmament Office as a consultant on military aviation in 1952 and became one of the principal officials tasked with building the German Air Force during the Cold War.  He became the German Military Representative to the NATO Military Committee in 1960, served as Acting Commander Allied Air Forces Central Europe in NATO 1965–1966, as Inspector of the Air Force 1966–1970 and as Chairman of the NATO Military Committee 1971–1974.  In retirement, Steinhoff became a widely read author of books on German military aviation during the Second World War and the experiences of the German people at that time. Kurt Welter (25 February 1916 – 7 March 1949) was a German "Luftwaffe" fighter ace and the most successful "Jet Expert" of World War II.  A flying ace or fighter ace is a military aviator credited with shooting down five or more enemy aircraft during aerial combat.  He claimed a total of 63 aerial victories—that is, 63 aerial combat encounters resulting in the destruction of the enemy aircraft—achieved in 93 combat missions.  He recorded 56 victories at night, including 33 Mosquitos, and scored more aerial victories from a jet fighter aircraft than anyone else in World War II and possibly in aviation history.  However this score is a matter of controversy; research of Royal Air Force losses suggests Welter overclaimed Mosquito victories considerably. The German Air Force (German: "Luftwaffe" (] ), the German-language generic term for "air force") is the aerial warfare branch of the Bundeswehr, the armed forces of Germany.  With a strength of 28,448 personnel (28 February 2017), it is the fourth largest air force within the European Union, after the air forces of the United Kingdom, France and Italy.  Although its budget has been significantly reduced since the end of the Cold War in 1989–1990, the Luftwaffe is still among the best-equipped air forces of the world. Wolfgang Thimmig (October 4, 1912—November 6, 1976) was a German Luftwaffe night fighter ace during World War II.  At the end of the war he had achieved no less than 24 aerial victories, reached the rank of Oberstleutnant and was Geschwaderkommodore for NJG 2, having previously been the Kommodore for NJG 4.  In 1956, Thimmig joined the newly formed Bundesluftwaffe and was the Military Attache of the Federal German Republic in Sweden between 1959 and 1963.  In addition to this he was the Nigerian Air Force's Chief of the Air Staff from 1965 to 1966.  He was the second Commander of the Nigerian Air Force (NAF), and assigned to the continuation of creating an Air Force for Nigeria by a 1963 agreement between Nigeria and Germany.  Thimmig and the German Air Force Assistance Group (GAFAG) withdrew from Nigeria in January 1966 when their task of creating an Air Force was completed. The Air Force Command (German: "Kommando Luftwaffe, Kdo Lw" ) is the high command of the German Air Force of the Bundeswehr as well as the staff of the Inspector of the Air Force.  It was formed in 2012, as a merger of the German Air Staff ("Führungsstab der Luftwaffe") with parts of the Air Force Office ("Luftwaffenamt"), and the Air Force Forces Command ("Luftwaffenführungskommando"), as part of a larger reorganization of the Bundeswehr.  The headquarters of the command are in Gatow, Berlin, but some of the staff is in Köln instead.
