Which statement best describes polar coordinates in artillery?

• A. They rely on map grid coordinates exclusively.
• B. They use latitude and longitude to locate targets.
• C. They specify distance and direction in terms of elevation and bearing.
• D. They specify distance (range) and direction (azimuth) from the observer.

Answer: (D)

Polar coordinates in artillery describe a target’s position from the observer’s point of view using two horizontal measurements: distance to the target (range) and the direction to it (azimuth). This pair lets the gun team specify where to fire without relying on a map grid or geographic coordinates. The range gives how far away the target is, and the azimuth provides the compass bearing from the observer to that target. Elevation is a separate setting for the gun’s angle of fire, not part of the polar coordinate location. Because of this, the statement that specifies distance (range) and direction (azimuth) from the observer best captures how polar coordinates are used in artillery.
