What air route fires are planned by the FSO to destroy, neutralize, or suppress known or suspected enemy positions?

• A. On call
• B. Preplanned
• C. Immediate
• D. Contingent

Answer: (B)

The concept being tested is planning horizon for fire support. Fires that are planned in advance are arranged as part of the operation plan, with targets, timing, and coordination with air assets already set. This fits the description of air route fires aimed at known or suspected enemy positions because the FSO is organizing and sequencing these engagements ahead of time to ensure proper airspace management, weapon choice, and synchronized effects. In contrast, on-call fires are requested during the operation in response to targets appearing, immediate fires are urgent responses to threats right now, and contingent fires depend on specific conditions or triggers. So, planning them in advance to address known or anticipated positions makes the preplanned option the best fit.
