What is the NATO common term for TADIL-J?

The NATO common term for TADIL-J is Link 16. This is a tactical data link that enables secure, jam-resistant communications among platforms such as aircraft, ships, and ground forces. TADIL-J enhances situational awareness and provides real-time data exchange for various military operations, making it critical for joint operations and interoperability among NATO forces. Link 16 operates within a frequency range that allows for higher data rates and more efficient use of bandwidth, which is essential for modern military communications.

Other options like Link 11 and Link 14 are older systems with different capabilities and functions. Link 11 is primarily used for air and naval forces to share tactical information, while Link 14 is designed for voice and data transfer between air and maritime units. Link 22 is a newer system that's meant to support beyond line-of-sight communications but is not the term associated with TADIL-J. Therefore, Link 16 stands out as the correct answer both in terms of functionality and its NATO designation for TADIL-J.
