What are the two ways the TDA passes engagement commands?

• A. Manual and Automatic
• B. Voice and Digital
• C. Voice and Text
• D. Digital and Video

Answer: (B)

Engagement commands need to reach the firing system through reliable channels that fit different situations. The TDA delivers those orders in two ways: voice, which is a real-time, human-to-human or operator-to-system channel through radio or handsets; and digital, a machine-readable path that sends encoded engagement data across the data link for precise, automated control within the fire-control network. Voice is fast for immediate coordination and clarification, while digital provides accuracy, traceability, and seamless integration with other system components. Other options don’t match how the TDA typically transmits commands, since they either describe modes of operation rather than transmission channels or mix in alternatives not used for this purpose.
