Chiamenti") is an inactive tank battalion of the Italian Army, which was based in Tauriano in Friuli-Venezia Giulia and last operationally assigned to the 132nd Armored Brigade "Ariete".

In January 1941, the battalion arrived in Libya to shore up the crumbling Italian 10th Army, which was disintegrating quickly due to the British Operation Compass.

On the same date the regiment formed five tank battalions, which were equipped with Fiat 3000 Mod.

On 24 January, the Special Armored Brigade battled the British 7th Armoured Division in the Action at Mechili.

By nightfall the Special Armored Brigade began its retreat to Antelat with the V Tank Battalion M13/40 as rearguard.

On 6 February, the retreating Italian formations found their escape route blocked by the British Combeforce at Beda Fomm and in the ensuing Battle of Beda Fomm the last remnants of the Italian 10th Army, including the V Tank Battalion M13/40, were annihilated.

On 8 February 1941, the V Tank Battalion M13/40 was declared lost due to wartime events.

Tank and armored battalions created during the 1975 army reform were named for officers, soldiers and partisans of the tank speciality, who had served in World War II and been awarded Italy's highest military honor the Gold Medal of Military Valor.

The 5th Tank Battalion was named for Marshal Carlo Chiamenti, who, while serving as platoon commander in the IV Tank Battalion M13/40, fell on 15 April 1941 during the Axis Invasion of Yugoslavia.

The three battalions were assigned to the 32nd Armored Brigade "Mameli", which was formed on the same day by reorganizing the command of the 32nd Tank Regiment.

[1][2] After the end of the Cold War Italian Army began to draw down its forces: on 1 April 1991, the 32nd Armored Brigade "Mameli" was disbanded and the 3rd Tank Battalion "M.O.

Chiamenti", and 23rd Bersaglieri Battalion "Castel di Borgo" were transferred to the 132nd Armored Brigade "Ariete".
