Which line-based format is used to pass target information to assets for engagement?

• A. 9Line
• B. DLER
• C. DLER or 9Line
• D. 5Line

Answer: (C)

Line-based targeting briefs standardize how target data is handed off to assets engaged in a fight. The 9Line is the classic, detailed briefing format used to pass critical information to air and fire support assets—location, target description, desired method of engagement, danger close, and other essential fields are organized in a clear, interoperable way. DLER is another line-based format used in some systems or units to convey the same essential targeting data digitally, just in a different structure. Because both formats can be used to communicate target information for engagement, the best answer acknowledges that either can be employed depending on the system in use. A five-line brief is typically too limited to capture all the necessary details for many engagements, so it isn’t the general right choice here.
