Which group should use tools such as military grid reference system maps, laser range finder equipment, and GPS devices to determine distances to visibility markers and create visibility aids/charts?

• A. Observing locations.
• B. Deployed locations.
• C. Control Tower.
• D. Aircraft Mishap.

Answer: (B)

In deployed locations, teams must rapidly establish accurate distances to visibility markers and turn that information into usable visibility aids or charts. Using a military grid reference system map provides a standardized way to reference positions on the ground, a laser range finder gives a precise distance to a marker, and GPS devices supply exact coordinates and distances. Together, these tools let you measure how far markers are and plot reliable charts that others can follow for safe navigation and coordination, even in temporary or unfamiliar terrain. This capability is why the deployed locations choice fits best. Observing locations focus on data collection, a control tower is an aviation‑control facility, and an aircraft mishap is an incident—none centers on producing visibility aids in a deployed setting like this.
