In March 1941, the regiment was reformed, but it remained in Vercelli for the rest of the war and was disbanded by German forces after the Armistice of Cassibile was announced on 8 September 1943.

Since then the regiment is tasked with managing the Capo Teulada Training Range and provide the opposing force for visiting units.

On 1 January 1938, the regiment received the XXIII Assault Tanks Battalion "Stennio", which had returned from Libya and took up residence in Fidenza.

The tankettes of the regiment attacked French positions in the Col du Mont Cenis sector.

After the French surrender the tank battalion advanced into Southern France, before returning to their bases in early July.

The regimental command retreated with the remnants of the Italian 10th Army along the Via Balbia, but British forces cut off the escape route at Beda Fomm.

For a short time the regiment was assigned to the 136th Armored Division "Giovani Fascisti", which was in the process of being formed.

However the regiment never deployed with the divisions, which was sent unfinished to Libya to shore up Axis forces fighting in the Western Desert campaign.

[2] Meanwhile, the regiment's IV Tank Battalion L, which had remained in Libya, participated in April 1941 in Operation Sonnenblume, during which Axis forces retook the Cyrenaica.

On 18 November 1941, the British Eighth Army commenced Operation Crusader, which broke the Siege of Tobruk threw Axis forces back to their starting positions at El Agheila.

The two companies were sent to Sicily, where they were assigned to the XVI Army Corps, which was tasked with the defence of the Southern part of the island.

However, on 8 September 1943, the Armistice of Cassibile was announced, and invading German forces disbanded the regiment and its depot.
