The information for a Regimental Headquarters 1939 is based on two publications. The establishment is based on War Establishment II/1931/7A dated 29 Jun 1938. The organisation is taken from Artillery Training Volume 1, Pamphlet No. 2A 1940. RHA, Field & Medium Regiments – Battle Drill and Manœuvre for the Reconnaisance and Occupation of Positions dated 6th March 1940. This is slightly different from the War Establishment tables. However, the field regiment organisation 1939 & 40 given in the Training Pamphlet is noted as being for guidance only.
