Which of the following is NOT a characteristic of tactical communications?

The correct answer is the characteristic that represents global communication capacity. Tactical communications are typically designed for specific operations and engagements rather than broad-spectrum or global coverage. These communications often emphasize localized, self-contained networks that can function in the field, tailored towards immediate operational needs and providing mission-specific functionalities.

Tactical communication systems are generally focused on enabling communication among forces at a command level, ensuring that teams can coordinate and execute their objectives effectively within a designated area. The emphasis is on efficient, reliable, and secure communication tailored to the mission's requirements rather than on a global scale. This makes tactical systems distinct from strategic communication systems, which are designed to support international or global operations.
