T/F: The designation 'S' is used at battalion and brigade levels.

• A. Sometimes
• B. Not used at those levels
• C. True
• D. False

Answer: (C)

The main idea is that headquarters at battalion and brigade levels are organized into staff sections that are labeled with S-n designations, where S stands for Staff. These S sections (such as S-1 for personnel, S-2 for intelligence, S-3 for operations, S-4 for logistics, and S-6 for communications, with others like S-5 or S-7 in some forces) handle the different functional areas needed to plan, coordinate, and support the unit’s activities. Because these staff elements exist at those echelons and use the S-n coding, the statement is true. Variations can occur between armies in exact numbering or naming, but the overarching convention—the use of S to mark staff functions at battalion and brigade HQs—remains.
