How does trajectory differ between high-angle and low-angle fire?

• A. High-angle fire uses a flatter trajectory with higher elevation.
• B. High-angle fire uses a steeper trajectory with lower elevation.
• C. Low-angle fire uses a steeper trajectory with higher elevation.
• D. High-angle fire uses a steeper trajectory with higher elevation; low-angle uses a flatter trajectory for longer range.

Answer: (D)

Trajectory is driven by how steeply you tilt the gun. Firing with a high-angle setup pushes the shell upward more, so the path climbs steeply, reaches a higher apex, and curves back down in a more pronounced arc. This means the projectile spends more time in the air and typically lands closer in horizontal distance than a flatter shot. It’s especially useful for dropping rounds onto targets behind cover or over obstacles. Firing with a low-angle setup tilts the barrel less, producing a flatter arc that stays closer to the line of sight, covers more horizontal distance, and therefore achieves longer range under similar conditions. So the statement that high-angle fire uses a steeper trajectory with higher elevation and low-angle fire uses a flatter trajectory for longer range captures the essential difference.
