1 Survey Battery Captain Culverwell commanded the section for several years and was followed by Captains H. D. W. Sitwell, C. L. Ferard, K. F. Mackay Lewis, W. J. Gyde and R. MacCaig. 1 Survey Section was reorganised in 1941 as the ‘Survey Troop’ and carried out the survey of the
Khyber Pass. In January 1942, it was re-designated as 1 Survey Battery under Major J. H. C. Hunter, and shortly afterwards re-joined the School of Artillery at
Deolali.
1st Indian Survey Regiment In August, 1942, the 1st Battery and a new Regimental Headquarters (R.H.Q.) were combined to form the 1st Indian Survey Regiment. The first Commanding Officer was Lieutenant-Colonel J. F. S. Rendall, with Major J. H. C. Hunter as Second-in -Command and Captain Matthews as Adjutant. Major S. A. Brighty commanded No. 1 Battery. In June, 1943, No. 2 Battery was formed under Major F. A. von Goldstein. A radar troop was raised in 1943 as part of the Regiment. One
Military Cross and three
Military Medals were awarded to personnel from the regiment. Orders had been issued that units not urgently required were to return to India and on 13 May 1945, the 1st Indian Survey Regiment was flown to
Comilla. Lieutenant-Colonel H. G. Croly was now in command and repatriation had begun, and many changes of all ranks were taking place. The regiment eventually moved to
Hyderabad (Sind) under Lieutenant-Colonel von Goldstein as commanding officer.
Partition On 25 January 1947, as a result of the
Partition, the 1st Indian Survey Regiment became
20th Survey Regiment, R.I. A., under command of Lieutenant-Colonel Rajbahadur, having shed 2nd Survey Battery. This became the 2nd Survey Battery, R.P.A. (later 13th Survey Battery, R.P.A.).
Post independence In July 1952, the Regiment was reorganised as the
20 Locating Regiment. In June 1987, the Regiment was redesignated as the
20 Surveillance and Target Acquisition (SATA) Regiment with the role of carrying out all weather surveillance of targets including enemy guns and mortars. ==Operations==
