Army OCS Call for Fire Practice Test 2026 – Complete Exam Prep

Shift from Known Point uses a fixed reference on the ground and describes how to move the fire from that point in four parts: Direction, Left/Right, Add/Drop, and Up/Down. Direction sets the general azimuth toward the target area from the known point, guiding the overall orientation of the shift. Left/Right provides the horizontal offset needed to move left or right of that line to align with the target. Add/Drop controls how much you change the range from the known point—whether you push farther out or pull closer in. Up/Down handles the vertical adjustment, changing the gun line to account for target height or ballistic needs. Together, these four elements let you complete a precise shift from the known point in both horizontal and vertical dimensions. The other options miss one or more of these components, so they don’t fully describe the shift from a known point.
