(iii) The earliest opportunity is to be taken (when four S.A.A. carts are empty, or sooner if necessary) to fill up empty carts from the divisional reserve. The brigade reserve should be regarded as available for the brigade generally, and also in case of necessity it will supply ammunition to any troops engaged.
(iv) Men and horses belonging to the brigade reserve are not to be sent to the divisional reserve.
Men and horses belonging to the divisional reserve are not to be sent further to the front than the brigade reserve, except in a case of emergency.
(v) Empty S.A.A. carts are to remain with the brigade reserve until they are replaced by full ones.
(vi) Receipts prepared by the officer in charge of the divisional reserve will be signed by the officer in charge of the brigade reserve for the number of full carts received by him.
(vii) After an action or during a pause in the engagement all deficiencies of ammunition must be made good from the divisional reserve.
7. Battalion arrangements for issuing extra ammunition.—Each company commander will detail one non-commissioned officer and two privates to act as ammunition carriers (if the company is strong, three privates should be detailed). Only men of strength and activity should be selected for this duty, the importance of which cannot be overrated.
Whenever a serious engagement is imminent, officer commanding battalions will issue to the men 50 rounds from the S.A.A. carts, so that, if possible, every man shall carry 150 rounds on his person. The extra ammunition should generally be issued before leaving the halting place of the previous night.
During an action every opportunity will be taken for supplying ammunition to the firing line by sending some up by carriers or with reinforcements. The carriers bring the ammunition from the pack animals (or from the S.A.A. carts) in canvas ammunition bags, and distribute it to the men in the ranks. The bags, when not in use, are carried on the pack animals. The loads are not to exceed 600 rounds to each carrier.
When more ammunition is required by the firing-line it will be taken forward by any men at hand, acting as carriers.
