'C' Medium Rgt, designated the 87th Medium Rgt from 18 August. The 63rd Medium Bty also absorbed 154 HAA Bty from 53rd (City of London) HAA Rgt. At first, the new regiment was under the command of the 9th AA Brigade at Poona then at Secunderabad. At the end of December, it arrived at Ranchi, the base of operations for the Burma Campaign, under the 101st Lines of Communication (LoC) area.

Here, the 63 Med Bty was detached from the regiment and moved into Burma.
