The L3/35 was developed from the Carden Loyd Mark VI tankette, four of which were imported from Britain in 1929.^[3] The first vehicle developed by the Italians from the Carden Lloyd tankette was designated CV-29; "CV" being an abbreviation of Carro Veloce (Italian: "fast tank") and "29" as the year of adoption. Only twenty-one CV-29s were built.^[4]

In 1933, a new design was built jointly by the Fiat Company of Turin and the Ansaldo Company of Genoa. This vehicle was introduced as the Fiat-Ansaldo CV-33. About 300 CV-33s were built.^[2]

In 1935, a slightly improved model of the CV-33 was introduced and designated CV-35. The primary differences were that the armour was bolted rather than riveted and the single 6.5 mm machine gun was replaced with twin 8 mm machine guns.^[2] Many older CV-33s were retrofitted to meet the specifications of the CV-35. In 1938, the vehicles were redesignated L3/33 ("L" for Leggero or 'light') and the L3/35.

In 1938, a further development of the L3 design was designated L3/38. The L3/38 had torsion bar suspension and two versions of a single mounted 13.2 mm machine gun.^[3]

Italy retrofitted at least 12 L3/35s to meet the specifications of the L3/38. The converted L3/35s with the L3/38's torsion bar suspension saw limited service in September 1943 until June 1944. These L3/38s versions of the L3/35s were armed with a single 13.2 mm Breda M31 machine gun.^{[citation needed]}

The L3/35 was a lightly armoured two-man vehicle typically armed with twin 8 mm machine guns, though variants were developed with other armament.^[2] Other than the number and type of machine guns, the differences between the L3/35 and the L3/33 were few. Both featured riveted and welded construction.

The vehicle's commander/gunner sat on the left and the driver sat on the right. The engine was mounted transversely in the rear.^[1] A circular radiator was mounted behind the engine. The transmission went to the front to the final drive. The Vickers-Carden-Lloyd type suspension had two three-wheel bogies on leaf spring and a single unsprung wheel on each side. There was an acacia wood^[a] rail that the top run of the tracks went on.^[1]

Between 2,000 and 2,500 L3 tankettes were built in different models and variants for the Royal Italian Army (Regio Esercito) and for other users.^[2] Twenty L3/33 tankettes were sold to China. Other L3 tankettes were sold to Afghanistan (unknown number), Albania (unknown number), Austria (72), Bolivia (14), Brazil (23), Bulgaria (14), Croatia (10), Hungary (65), Iraq (16), Nationalist Spain, and Venezuela (2).^[2] Many foreign buyers substituted other machine guns as the main armament. The Hungarians added a raised commander's vision cupola to 45 of the L3s they acquired. In 1937, the Brazilian Army ordered 18 L3/35 tankettes, designated Auto Metralhadora de Reconhecimento^[5] which remained in active service until 1945 when some units were resold to the Dominican Republic. Venezuela bought two units in 1934 for evaluation in infantry support operations, because of several incidents on the border with Colombia, like other weapons acquired from the Italian mission they did not survive past World War II.

In addition to seeing action in the Second Italo-Abyssinian War, the Second Sino-Japanese War, the Spanish Civil War, the Slovak-Hungarian War, and the Anglo-Iraqi War, the L3 was used almost everywhere that Italian troops fought during World War II.^[1] L3s were found on the Italian/French border, North Africa, Italian East Africa, the Balkans, USSR, Sicily, and Italy.^[2]

The combat performance of the L3s during the interwar period was poor. On at least two occasions during the Italian invasion of Ethiopia, L3s were put out of action by massed infantry attacks. In the Spanish Civil War, L3s of the Corps of Volunteer Troops (Corpo Truppe Volontarie, or CTV) were totally out-classed by the T-26 and BT-5 tanks provided to the Republican forces by the Soviet Union. The L3s were not a factor in the brief war between Hungary and Slovakia in 1939.^{[citation needed]}

On 10 June 1940, when Italy entered World War II, the Royal Italian Army (Regio Esercito) possessed only about one-hundred M11/39 medium tanks in two tank battalions. L3 tankettes still equipped all three Italian armoured divisions, the tank battalions in the motorized divisions, the light tank squadron group in each "Fast" (Celere) division, and numerous independent tank battalions.

On 22 March 1941, two Iraqi L3s were reported to have been put out of action near Fallujah during the Anglo-Iraqi War.

More than 40 captured L3 tankettes were used by the Greek Army during the Greco-Italian War, fought from 1940 to 1941, and were used to equip the 19th Mechanized Division, although they did not take part in combat with the latter. After the invasion of Yugoslavia and Greece in April 1941, L3 tankettes were also captured by the Yugoslav and Greek resistance forces. From 1941, some L3 tankettes were given to the Italo-German puppet government of the Independent State of Croatia (Nezavisna Država Hrvatska, or NDH).

Though numerous, Italy's tankettes proved to be outclassed from the start and also proved to be of low tactical value. They were vulnerable to the British Boys anti-tank rifles.^[6] Other than those used for occupation duties in the Balkans and elsewhere, few L3s remained in front line service past the end of 1940. After the Italian armistice with the Allies in 1943, L3 tankettes were used by German Army forces and by the pro-Nazi National Republican Army of the Italian Social Republic. Hungarian L3s had by this point been issued to the Gendarmerie.

L3/35s also joined the Chinese Nationalist Army fighting against the Japanese Imperial Army during the Second Sino-Japanese War and the Communists during the Chinese Civil War.

The L3/35 appeared in several variants including an anti-tank variant and a flame thrower variant.

The "L3 cc" anti-tank (controcarro) was an L3 with a Solothurn 20 mm anti-tank rifle mounted in place of its normal machine gun armament. Only a few were so modified, and they saw action only in North Africa.^[1]

The Solothurn rifle could penetrate up to 18 mm of armor at 300 m (328 yards) which was effective against lightly armoured vehicles.^[7]

Development of the "L3 Lf" flamethrower (lancia fiamme) flame tank began in 1935. The flamethrower nozzle replaced one of the machine guns, and the flame fuel was carried in an armoured 500-litre (133 US gallons) fuel trailer towed by the vehicle. Later versions carried another 60 litres of fuel in a box-shaped tank mounted above the L3's engine compartment. The vehicle weighed 5 metric tons.

The L3 Lf saw action in Abyssinia, Spain, France, the Balkans, North Africa, and Italian East Africa. From 1936 each CV/L3 company had a single L3 Lf platoon.^[8]

The basic L3 platform was also employed as a command vehicle using the Marelli RF1 CA radio in platoon and company command vehicles. The L3 was considered too small to be effectively employed as a regimental level command radio vehicle so this task fell to the later and slightly larger L6/40 CR (Centro Radio = Radio Center).^[8]

The few L3 Passerella (bridge layer) vehicles constructed were assigned to units at Armoured Brigade levels. The 7-meter-long (23 ft) bridge was stripped down into sections on a trailer towed by the L3 itself for travel. On arriving at the combat zone, this bridge was assembled on the front of the tank, suspended by cables from two small cranes located over the crew's superstructure. The crew laid the completed bridge over the obstacle from within the vehicle. A L3 Passerella crew took seven minutes to lay out this bridge.^[9]

A single Savoia-Marchetti SM.82 aircraft was modified to carry a L3/33 recessed under the fuselage for experiments with airborne armour.^[10]

Unarmed armoured recovery vehicle with a rear tow bar, did not progress beyond the prototype stage.^[10]

Tank destroyer with a 47 mm L/32 gun mounted in the hull, based on the L3/35. At least one built but did not enter service.^[10]

Tank built by Fiat-Ansaldo in 1937 on the L3/33 chassis with a redesigned hull and a 20 mm gun in a rotating turret. Did not enter serial production.^[10]

On 8 August 1937, Major General García Pallasar had received a note from Generalísimo Francisco Franco which expressed the need for a Panzer I armed with a 20 mm gun. Although originally forty Italian L3/35 tankettes were ordered with the original armament exchanged for the 20 mm Breda Model 35 instead, this order was subsequently cancelled after it was thought that the adaptation of the same gun to the German Panzer I would yield better results.^[11]
