In the ‘new’ Divisional Artillery ‘universal establishment’ structure, the Divisional Ammunition Columns reorganized around a new supporting model, standing up a dedicated ‘A’ Echelon, and a supporting ‘B’ Echelon. The ‘A’ Echelon comprised four ‘new’ Sections, now doing the work of the (four) Brigade Ammunition Columns, one for each of the Division's 'mixed' Artillery Brigades. Each common 'A' Section, had the same task of bringing forward ‘first-line’ artillery ammunition, and small arms ammunition, to the batteries of an affiliated Artillery and Infantry Brigade, as previously did a Field BACs.
