field regiments had been organised in 1938 into two 12-gun batteries. the experience of the bef in 1940 showed the problem with this organisation: field regiments were intended to support an infantry brigade of three battalions. this could not be managed without severe disruption to the regiment. as a result, field regiments were reorganised into three 8-gun batteries. the third battery (470th) was formed in the regiment at great baddow in march 1941.
