II. Gruppe under command of Hrabak was moved to Trakehnen on 20 June 1941.[8] The Wehrmacht launched Operation Barbarossa, the invasion of the Soviet Union, on 22 June with II. Gruppe supporting Army Group North in its strategic goal towards Leningrad.[7] On the first day of the invasion, II.

Two days later they moved to Dünaburg, present-day Daugavpils, where Hannig claimed an Ilyushin DB-3 bomber shot down. On 28 June, the 8th Panzer Division had established a bridgehead across the Daugava. Operating from Dünaburg over the bridgehead, Hannig claimed a SB-2 bomber shot down on 30 June, three SB-3 bombers on 2 July, and another SB-2 bomber on 6 July. The following day, III.

On 20 January 1942, the Gruppe began relocating to the Eastern Front where they would be based at Siverskaya near Leningrad.[18] Flying missions over the Volkhov, Hannig claimed his first aerial victory in 1942 over an I-18 fighter on 5 February.[19] Operating from Siverskaya during the Battle of Lyuban, Hannig claimed five further aerial victories.

He then claimed a Petlyakov Pe-2 bomber on 23 February.[20] Hannig then claimed a Lend-Lease Curtiss P-40 Warhawk fighter on 5 March followed by an I-18 fighter on 15 March.[21]

On 20 March, II. Gruppe moved to Rjelbitzi Airfield, located 26 kilometers (16 miles) north of Dno and 15 kilometers (9.3 miles) west-southwest of Soltsy on the northern bank of the Shelon. Here, the Gruppe supported German forces fighting in the Demyansk Pocket and Kholm Pocket.[22] In late March and April 1942, Hannig claimed further twelve aerial victories, increasing his total to 48 aerial victories claimed.[23] Here on 7 May, Hannig claimed a Yakovlev Yak-1 fighter shot down.[24] On 9 May 1942, Leutnant (second Lieutenant) Hannig was awarded the Knight's Cross of the Iron Cross (Ritterkreuz des Eisernen Kreuzes) having flown over 200 operations and claiming 48 victories. He and Leutnant Hans Beißwenger received the Knight's Cross from General der Flieger Helmuth Förster at Siverskaya.[25][26] Following the Knight's Cross presentation, Hannig claimed his next aerial victory on 11 May when he shot down a Mikoyan-Gurevich MiG-3 fighter in the Demyansk combat area. He then shot down two Lavochkin-Gorbunov-Gudkov LaGG-3 fighters, one on 15 and 18 May each.[27]

In July 1942, II. Gruppe was re-equipped with the Bf 109 G-2. Hannig then claimed a Yak-1 fighter shot down near Zaluchye located approximately 40 kilometers (25 miles) west of Demyansk on 7 July.[28] On 24 July, he claimed his 54th victory, an Ilyushin Il-2 ground-attack aircraft near Lychkovo located southeast of Lake Ilmen.[29][Note 2] On 12 August, 5.

On 7 October, Hauptmann Joachim Wandel, the commander of 5. Staffel was killed in action. In consequence, Hannig succeeded Wandel as Staffelkapitän (squadron leader) of 5. Staffel the following day.[35] In early November, the Gruppe fought in the combat area north of Demyansk. Here, Hannig claimed his last aerial victories on the Eastern Front on 5 November. Taking his total to 90 aerial victories claimed, he was credited with destroying four LaGG-3 fighters that day.[36] Three of which on one mission.[37] On 28 September in aerial combat, Hannig flew his Bf 109 G-2 (Werknummer 10366—factory number) into the ground near Andronovo.[38] Hannig was then transferred to the Western Front and command of 5. Staffel was passed on to Hauptmann Paul Steindl.[35]

On 27 January 1943, Hannig was appointed Staffelkapitän of 2. Staffel of Jagdgeschwader 2 "Richthofen" (JG 2—2nd fighter fing) based in France. He replaced Oberleutnant Christian Eickhoff who had been killed in action the day before. The Staffel was subordinated to I. Gruppe of JG 2 headed by Major Helmut-Felix Bolz.[39] While serving with 2.

On 16 February, the USAAF VIII Bomber Command attacked Saint-Nazaire. I.

On 28 March, bombers of VIII Bomber Command escorted by Supermarine Spitfire fighters headed for Rouen. I.

His grave at the Saint-Désir-de-Lisieux German war cemetery.

The Royal Air Force (RAF) targeted the Caen-Carpiquet Airdrome on 15 May 1943. Defending against this attack, elements of I. Gruppe intercepted the RAF fighters and claimed four aerial victories, two of which were not confirmed. Hannig was credited with the destruction of a Spitfire shot down east of Troarn, his 98th aerial victory.[42] In this engagement JG 3 lost four aircraft with three pilots killed in action, including Hannig.[43] He was shot down in his Focke-Wulf Fw 190 A-4 (Werknummer 0734) near the airfield at Rocquancourt.[44] His victor was Squadron Leader J. Charles leading Yellow Section of No. 611 Squadron. He had managed to bail out but his parachute failed to open.[45][46] Hannig was posthumously awarded the 364th Knight's Cross of the Iron Cross with Oak Leaves (Ritterkreuz des Eisernen Kreuzes mit Eichenlaub) on 3 January 1944 and posthumously promoted to Oberleutnant (first Lieutenant). He was interred at the Saint-Désir-de-Lisieux German war cemetery.[47] He was succeeded by Oberleutnant Karl Haberland as commander of 2. Staffel.[39]

According to Obermaier and Spick, Hannig was credited with 98 aerial victories, 90 on the Eastern Front and 8 on the Western Front, claimed in over 350 combat missions.[5][48] Mathews and Foreman, authors of Luftwaffe Aces — Biographies and Victory Claims, researched the German Federal Archives and found documentation for 97 aerial victory claims. This number includes 90 on the Eastern Front and 7 on the Western Front, including one four-engined bomber.[49]

Victory claims were logged to a map-reference (PQ = Planquadrat), for example "PQ 54251". The Luftwaffe grid map (Jägermeldenetz) covered all of Europe, western Russia and North Africa and was composed of rectangles measuring 15 minutes of latitude by 30 minutes of longitude, an area of about 360 square miles (930 km²). These sectors were then subdivided into 36 smaller units to give a location area 3 km × 4 km (1.9 mi × 2.5 mi) in size.[50]
