Starting in March 1942, she served in the
Red Army. In May, she was appointed the first commanding officer of the
101st Long-Range Aviation Regiment, which consisted of about 300 men: pilots, navigators, engineers and ground support personnel. Her unit was equipped with
Lisunov Li-2 transport aircraft (license-built versions of the
Douglas DC-3) with pilots conscripted from the Civil Air Fleet. Grizodubova's Li-2s had a
crew of six
aviators: pilot,
co-pilot,
navigator, flight-technician,
radio operator and
air gunner. The unit initially had the task of bombing enemy troops, then flying to
partisans and in June 1942 helping supply the besieged
Leningrad. Subsequently, the 101st Long-Range Bomber Air Regiment was ordered to bomb
Wehrmacht units that had broken the
Bryansk and South-Western Fronts and were heading for
Voronezh. Grizodubova led her regiment almost every night, overcoming strong
flak defences and
Luftwaffe night fighters in the
Kursk,
Orel, and
L'gov areas. In September 1942 the 101st Long-Range Aviation Regiment was placed at the disposal of the
Central HQ of the Partisan Movement. The unit flew more than 1,850 sorties to partisan-held areas, delivering about 1,500 tons of arms and ammunition and hundreds of tons of radio equipment, printing presses, film cameras, and reading material for Soviet partisan leaders. The Regiment also evacuated 2,500 wounded partisans and homeless orphans. However, poor airstrips and enemy fighters were a constant threat to the Li-2s and their crews. On Grizodubova's initiative, by March 1943 partisans had built an improved airstrip on the right bank of the
Dnieper, where up to a dozen aircraft could be parked in daytime. On 27 May 1944 her regiment was awarded the honorific title ''Krasnosel'skiy'' for participating to break the siege of Leningrad. By the time Grizodubova was recalled to Moscow, in June 1944, she had flown about 200 sorties. Two months later, on 30 August, the 101st Long-Range Aviation Regiment was awarded the Order of the Red Banner and, later, the honorific of "Guards". ==Post war==
