Martinoli gained a glider pilot's licence in 1937. The following year, he was enlisted in the Regia Aeronautica, and after a military flying course at Ghedi, was assigned to 366ª Squadriglia of 151° Gruppo (53°Stormo) with the rank of Sergente Pilota.^[2] Subsequently, he was posted to the 384ª Squadriglia, 157° Gruppo, stationed in Trapani, Sicily.^[2]

North Africa edit

He claimed his first air victory, just three days after Italy entered the war, on 13 June 1940. His apparent first victim was a bomber, most probably a French Potez 630, shot down over Tunis, while flying his Fiat CR.42. This encounter is unverified from any other source however Martinoli's own log book has a precise attesting entry in it.^[3] Then he was posted to 78ª Squadriglia, 13° Gruppo of 2° Stormo and on 13 October he claimed a Gloster Gladiator (most probably from No. 112 Squadron RAF), while escorting a Savoia-Marchetti S.79, to Mersa Matruh, Egypt. Having transferred to 4° Stormo, Martinoli claimed a Bristol Blenheim shot down in the Bardia, Libya zone on 5 January 1941.^[3]

Malta edit

After he had transferred to 4° Stormo (which became his permanent unit), in autumn 1941 Martinoli flew fighter sweeps over Malta, from Comiso in Sicily. Flying the Macchi C.202, in just two months, he claimed three Hurricanes (two on 19 October 1941) and a Blenheim. Still over Malta, he was credited with the destruction of three Spitfires (plus one probable) between 4 and 16 May 1942.^[4] Back in North Africa, during the Battle of Bir Hacheim, on 9 June 1942, he shot down two P-40 fighters and damaged a third.^[5] On 29 June, in Marsa Matruh area, along with three more 73ª Squadriglia Macchi C.202s, he attacked a formation of 12 P-40s, downing a Curtiss fighter (while his fellow pilots shot down two more).^[6] Martinoli's final kill in the North Africa theatre was over El Daba on 23 October 1942. Officially, this was identified as a Bell P-39 Airacobra but was more likely a Curtiss Kittyhawk from No. 260 Squadron RAF.^[3]

During the summer of 1943, he took part in the defence of Sicily and Italy.

On 4 July, he claimed a P-38 Lightning and a shared Boeing B-17 Flying Fortress over Sicily.

After the armistice of 8 September, he joined the Aeronautica Co-Belligerante (Co-Belligerent Air Force), fighting alongside the Allies. He flew, with other 4° Stormo pilots, sorties to Yugoslavia, attacking the German Wehrmacht and Luftwaffe. He shot down a Junkers Ju 52/3m over Podgorica, on 1 November 1943, after a dogfight with two Messerschmitt Bf 109s. It was his last air victory.

He was killed in a flying accident on 25 August 1944, at Campo Vesuvio air base, while training on one of the second-hand Bell P-39s that had just been delivered to the Co-Belligerent Air Force.^[7]

Martinoli was posthumously awarded the Medaglia d'oro al Valor Militare (Gold Medal of Military Valor). He had been previously decorated with two silver medals and the German Iron Cross Second Class.
