Which planning range of a SINCGARS radio is classified as HI?

The HI range classification for a SINCGARS radio is identified as 5-10 kilometers. This range indicates the capability of the radio to effectively communicate over substantial distances, which is critical for military operations where maintaining secure and reliable communications is essential.

In the context of SINCGARS (Single Channel Ground and Airborne Radio System), different ranges are assigned to categorize the effective transmission distances. The HI range allows for operations in a broader tactical environment, enabling units to maintain contact over distances that align with operational needs.

The operational effectiveness in this range supports mission coordination and situational awareness, making it a vital aspect of superior battle management.
