With the development and fielding of satellite communications throughout the U.S. military, today’s warfighters rarely use high frequency communications within and between units. International events have increased interest in high frequency communications as an alternative to connecting via satellites on current and future battlefields. U.S. military units already own a large amount of the radio equipment suitable for employment at various levels of the battlefield and for humanitarian relief as a redundant means of beyond-line-of-sight communications.

The Russian military has been using a clever—and lethal—propaganda technique against Ukrainian soldiers. They spam the soldiers’ cellphones with demoralizing messages and then take advantage of the resulting confusion to geolocate the soldiers’ cellphone signals and launch an attack.
Gen. Baker: You're never going to be able to emulate [in training] the gut-wrenching emotions of Russian-style messaging.#AFCEATechNet

The National Institute of Standards and Technology (NIST) has created a robotic arm that is being used to measure the properties of antennas rapidly and accurately. The robot, formally named the Configurable Robotic Millimeter-Wave Antenna facility, may be the ultimate innovation, extending measurements to higher frequencies while characterizing antennas faster and more easily than previous NIST facilities.
