In particular, the 2-pounder Anti-Tank Battery in the Light Artillery Brigade was now to come from a Divisional Anti-Tank Brigade; the Ammunition Sections became 'Q' instead of'T'; mortars were shown as optional instead of howitzers in the Divisional Light (Pack) Battery; the Rifle Regiments in the Mounted Brigade became Commandos; and the 'Q' Services were reorganized and absorbed the Labour Battalion.
