If necessary, the BCT fires cell and cannon field artillery battalion command post personnel resolve conflicts due to technical fire control considerations using the brigade FSO’s initial schedule of fires. Schedules of fire may be prepared for any circumstance depending on the situation. Some schedules that may be prepared include: Groups (see figure 6-6 on page 6-42). Series (see figure 6-7 on page 6-43) Programs (see figure 6-8 on page 6-44). Smoke and Illumination (see figure 6-9 on page 6-45). Preparations. Counterpreparations. Harassing. Interdiction. 6-155. Prepare a separate DA Form 4656 (Scheduling Worksheet) for each schedule of fire. The worksheet is the fire planner’s tool for manually organizing the targets on the targeting worksheet into specific schedules. The DA Form 4656 (Scheduling Worksheet) provides: A specific sequence during which the targets scheduled will be engaged. Targets requiring more than one volley. These are scheduled at the sustained rate of fire for the weapon system being used. The total expenditure of ammunition by each firing unit on each target. The shell-fuze combination for each target if it deviates from the standard of high explosive (HE) with quick fuze. Any on-call targets that are to be engaged. Any special instructions. The fire support assets available. 6-156. Unless otherwise indicated in the REMARKS column, all targets will be engaged with HE with quick fuze. For planning purposes, the schedule reflects the time of impact for all targets. Targets that
