You are the Support Operations Officer for a Sustainment Brigade supporting a Division attack to seize key terrain. The Division Sustainment Plan requires emergency resupply of artillery ammunition at multiple locations simultaneously. However, you have limited truck assets available. To ensure continuity of support, you should: A. Split available trucks evenly between the resupply locations and continue to push ammunition as long as the routes remain open. B. Focus all assets on resupplying the artillery unit closest to the Sustainment Brigade first before moving to the next location. C. Request additional heavy equipment transports (HETs) from the Theater Sustainment Command to augment your trucks. D. Schedule resupply in phases to each artillery unit in turn based on the pace of their ammunition expenditure
