Leonzio Bicego was born on 22 April 1918 and was from San Giovanni In Persiceto.

In November 1941, Bicego belonged to 23^o Autonomo C.T., based at Pantelleria off Sicily. At this time the unit was equipped with Fiat CR.42s.

Blenheims were out from Malta on 11 December 1941, three of them attacking a 5,000 ton vessel in Argostoli harbour. The aircraft of Flight Lieutenant E. G. Edmunds of 18 Squadron failed to return, and it would seem that this fell afoul of two 23^o Gruppo CR.42s flown by Maresciallo Germano Gasperoni and Sergente Bicego. They had taken off during the morning to escort some S.82 transport aircraft to Tripoli, and claimed a Blenheim shot down between them. Gasperoni returned with his aircraft damaged and a wound in his left arm.

Sergente Bicego was decorated with his first Medaglia d’argento al valor militare (gazetted 1942) for the combat on 11 December 1941:

"An extremely young, bold, and generous fighter pilot, he repeatedly demonstrated his courage during long escort flights over open sea. While on a transport protection mission, he sighted and decisively attacked an enemy aircraft. Ignoring the intense return fire that repeatedly struck his plane, and after his section leader was forced to withdraw from the fight due to injuries, he continued the battle alone until he successfully shot down the enemy aircraft over the sea."
Central Mediterranean skies, 11 December 1941 - XX.

Post-war and posthumously, Sergente Bicego was decorated with a second Medaglia d’argento al valor militare (gazetted 1956) for his actions over the Mediterranean between 10 August 1941 and 29 December 1942:

"A fighter pilot who carried out numerous combat actions and missions, always completing them brilliantly. In every circumstance, he demonstrated exemplary aggressiveness and bravery." Mediterranean skies, 10 August 1941 – 29 December 1942.

On 3 February 1943, nine B-24s of the 376th BG set out to attack Palermo harbour, (three of which returned early).
The Regia Aeronautica recorded that a raid by heavy bombers was made on Sicily. At Palermo three MC.202s of the 377^a Squadriglia were scrambled, Sottotenente Luigi Torchio (MC.202 MM7712/377-1) reporting to have engaged three P-38, claiming one shot down (17:10-18:15) and one probable (17:30). Sergente Leonzio Bicego then attacked three four-engine bombers, claiming hits on the leading aircraft, between the cockpit and the inner left engine, noting this as probably shot down at 17:30. Finally, Sergente Maggiore Giordano Migliavacca made repeated attacks on an aircraft on the left of the formation which he claimed to have shot down at 17:45, reportedly two members of the crew being seen to bale out. However, it seems that this claim only was credited as a probable.
Sottotenente Torchio was wounded in this combat and his aircraft being damaged, forcing him to belly-land at Palermo.
No Allied losses seems to have been recorded at this time.

14 P-38s of the 27th FS, 1st FG, escorted 38 B-17s from the 97th BG and 301st BG to attack Palermo docks in the early afternoon on 1 March 1943, where the Italian destroyer Geniere was sunk. Some smaller vessels were also lost in this raid including the ferry barge MZ 741, the tug Porto Adriano (230 tons) and the ferry Lampedusa (505 tons).
Seven MC.202s of the 377^a and 372^a Squadriglie were scrambled to intercept, their pilots claiming two B-17s shot down and a third probable (reportedly at 16:30). From 377^a Squadriglia Tenente Luigi Torchio claimed one destroyed B-17 and Sergente Maggiore Mario Mocchiuti claimed the probable. Sergente Maggiore Mario Sandini (372^a Squadriglia) claimed the second B-17 but his MC.202 was hit and he was wounded. Sergente Maggiore Giordano Migliavacca (377^a Squadriglia) was also wounded when his MC.202 was damaged while Sergente Bicego (377^a Squadriglia) was killed when his MC.202 (MM7793) was shot down.
Between 14:05-15:13, one Italian fighter, identified as an MC.200, was claimed shot down over Palermo by 1st Lieutenant John L. Wolford of 27th FS. The gunners of 97th BG claimed two Bf 109s over Palermo at 13:30 while gunners from 301st BG claimed one probable and three damaged at the same place and time. The claims from 301st BG were made against a mixture of Bf 109s, FW 190s, MC.200s and Re.2001s and made by:
Gunner in pilot Medeley’s B-17F 41-24348 from 352nd BS, who claimed one damaged
Gunner in pilot Larkin’s B-17F 42-5068 from 353rd BS, who claimed one probable
Gunner in pilot Lundell’s B-17F 42-5134 from 353rd BS, who claimed one damaged
Gunner in pilot Rolf’s B-17F 41-24364 from 353rd BS, who claimed one damaged
No US aircraft were lost.

At the time of his death, Bicego was credited with 1 shared biplane victory, this one being claimed while flying Fiat CR.42s.

After his death, Sergente Bicego was decorated with a posthumous and third Medaglia d’argento al valor militare (gazetted 1943) for the combat on 1 March 1943:

"A young and daring fighter pilot, already distinguished in previous wartime actions, always the first to volunteer for any combat mission. During a fierce raid on our naval base, he launched an attack against an overwhelmingly large enemy formation, diving into its midst without regard for the intense counterfire. Fatally hit, he plunged into the sea, fulfilling his duty to the utmost. A shining example of noble warrior virtues, heroic youth, and a readiness to give everything for the greater glory of the Armed Fatherland."
