The British field regiment in early 1940

A field regiment was originally equipped with 4.5in howitzers and 18pdr guns. As 25pdr production was still ramping up, 18pdr carriages were converted with 25pdr gun-howitzer barrels. This was the "18/25pdr". A field regiment had a complement of 580 officers and men. They were armed with 75 pistols, 113 rifles, 14-LMG, and 13 Boys anti-tank rifles. After the collapse of the front in May 1940, they apparently fought as infantry on the way to withdrawal at Dunkirk.
