I've just posted an article on the role of 1st Battalion DLI as the Machine Gun Battalion in the 6th Brigade of the 2nd Division between 1934 and 1936. Much less heralded than the Experimental Mechanised and Armoured Forces it did however exert considerable influence on the infantry formations with which the British entered WW11. It is posted on my Interwar Tank Development blog (I know but it is the most relevant one) here. Organisational tables for the battalion for 1935 and 1936 are attached. With grateful thanks to Peter Nelson of the DLI Collection and of this Forum for his help with identifying research sources.
