What is the name of the combination of radio and landline signals that sends tactical information around the battlefield?

The combination of radio and landline signals that sends tactical information around the battlefield is referred to as Tactical Data Link (TDL). TDL systems are designed to facilitate real-time communication and data sharing between various military assets, enhancing situational awareness and operational effectiveness. These links allow different platforms, such as aircraft, ground vehicles, and naval units, to exchange critical information efficiently, leading to improved coordination and decision-making during operations.

Other options may represent different types of communication systems or networks, but TDL specifically addresses the integration of multiple data communication methods for tactical applications on the battlefield. This specialization makes TDL essential for maintaining connectedness among diverse military forces in complex and dynamic environments.
