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

A range card is a map or notebook that records known targets and their firing data to help guns adjust and fire accurately. It links each target’s location to the aiming data—bearing, range, and the required elevation/deflection—and tracks corrections after each shot so subsequent rounds hit more precisely. This practical reference lets the gun crew quickly translate observer inputs into accurate fire, and it keeps targeting information organized for coordinated fires. The other options describe weather data, ammo/roster records, or maintenance scheduling, which aren’t about targeting or adjusting fire.
