What is a Primary Target Line (PTL)?

• A. Sector of Fire
• B. Engage
• C. PTL
• D. Weapons Assignment

Answer: (C)

The Primary Target Line is the reference line from the fire-control system or sensor to the primary target—the direction you must aim along to engage that target. It defines the line of sight and the path along which the weapon must be directed to place rounds on the primary target, and it’s used to generate the firing solution, including lead and deflection. This line serves as the common reference for engagement planning: you designate one target as primary, and the system uses the Primary Target Line to ensure the primary target is tracked and attacked first, while other targets are managed separately. In short, the Primary Target Line is about the target’s direction and the corresponding aim path for the primary engagement, not about the overall sector of fire, a command to engage, or how weapons are assigned.
