A standardized radio transmission format used by JTACs, FACs, and AFACs to relay target information to aircraft conducting Close Air Support (CAS) missions. The 9-Line ensures that pilots receive all essential details in a concise, structured format, minimizing confusion and maximizing safety during high-stakes operations.
The nine standard elements are:
- IP/BP (Initial Point/Battle Position): The location from which the aircraft begins its attack run.
- Heading: Magnetic heading from the IP to the target.
- Distance: From the IP to the target, in nautical miles.
- Target Elevation: Altitude of the target in feet above mean sea level (MSL).
- Target Description: Short, clear description (e.g., “Two tanks in the open, stationary”).
- Target Location: Coordinates of the target (grid, lat/long, etc.).
- Mark: How the target will be marked (e.g., smoke, laser, IR pointer).
- Friendlies: Location of friendly forces relative to the target.
- Egress: Instructions for how the aircraft should exit the target area after the attack.
Additional remarks may include threats, restrictions, laser codes, ordnance requests, or final attack headings. The JTAC typically ends with “Cleared Hot” or “Cleared to Engage”.
Application in DCS World
- AI JTAC units in DCS provide simplified 9-Line briefs via the comms menu, covering target location, mark, and attack clearance. Laser designation and smoke marking are supported.
- The DCS AI 9-Line is abridged and lacks some details (IP/BP, egress, altitude restrictions). It’s also menu-driven, not a natural voice transmission. Real-world brevity and flexibility are absent unless played by humans.
Cadets should first practice with AI JTAC 9-Lines to understand the sequence, then move to multiplayer training with human JTAC/FAC/AFACs over SRS. This develops true CAS communication skills and prepares pilots for realistic CAS integration.
