In 1938 the RA modernised its nomenclature and a lieutenant-colonel's command was designated a 'regiment' rather than a 'brigade'; this applied to TA field brigades from 1 November 1938. The TA was doubled in size after the Munich Crisis, and most regiments split to form duplicates. Part of the reorganisation was that field regiments changed from four six-gun batteries to an establishment of two batteries, each of three four-gun troops. 85th (East Anglian) Field Rgt formed 134th Field Rgt as its duplicate from 24 June 1939:Farndale, Years of Defeat, p. 9.Sainsbury, pp. 17–20; Appendix 2.
