The regiment was raised on 15 May 1940 as 'B' Field Brigade, Indian Artillery at Bangalore by Lieutenant Colonel (later Brigadier) Guy Horsfield.

Late in the evening of 26 May, 2 Field Regiment was warned of an impending attack by Rommel's forces early next morning.

The defences at Point 171 were incomplete, without mines, uncoordinated and without any tanks deployed in the Brigade Box area, but were ready to face the might of the Germans.

In the battle, despite being surrounded from all sides by German Panzers, the gunners showed indomitable spirit and courage and destroyed many tanks (estimated 52–64).

[7][8] The ferocity of the battle can be gauged from the numbers of enemy tanks destroyed as also from the fact that the losses suffered by 2 Field Regiment included six officers and many men killed, and many wounded or taken prisoners of war.

After a short three weeks rest at Kalemyo, the regiment joined 7th Indian Infantry Division, IV Corps at Pokokku.

[19] On 23 February 1945, the Regiment was positioned in defence near Letse (east of Arakan), Burma; when the Japanese launched a Brigade attack.
