In indirect fire, which parameters are adjusted to align with the target location?

• A. Elevation, deflection, and/or charge.
• B. Ammunition type and fuse setting.
• C. Barometric pressure and temperature.
• D. Number of rounds in the battery.

Answer: (A)

In indirect fire, you align with the target by adjusting three things that directly shape where the round goes: elevation, deflection, and the propellant charge. Elevation sets the vertical angle, determining how high the projectile climbs and how far it travels in the vertical plane. Deflection moves the gun horizontally, steering the tube toward the target bearing. The propellant charge changes the muzzle velocity, which affects the range the round will cover at that angle. Together, these adjustments align the firing solution with the target location.

Ammunition type and fuse setting influence the projectile’s effect and timing after impact, not where it lands. Barometric pressure and temperature feed ballistic calculations but aren’t the manual adjustments used to place a round on target. The number of rounds in the battery is a supply factor, not an aiming adjustment.
