The line that contains the "kill chain" authorities is which line in the STO data structure?

• A. Line 1
• B. Line 3
• C. Line 2
• D. Line 3A

Answer: (B)

Focusing on how authorities are organized in the STO data structure, the line that holds the kill chain authorities is the line dedicated to execution and engagement decisions. This is the third line, as it gathers the operational authority needed to move from detection through to action within the kill chain. A subline like 3A sits under that line, but it isn’t the primary container for the kill chain authorities itself. The other lines cover different authority domains (planning/coordination, oversight, etc.), not the direct execution authority required to engage targets.
