The US Army put new battlefield tech to the test. Now it's deciding what isn't making the cut.

Major parts of NGC2 will move forward, scaling to different units for testing and use. US Army photo by Sgt. Kayla Cheesman-Miles The US Army is deciding what worked and what failed in a major test of its new command system. The parts that worked will now be rolled out to more units for further testing and training. Some systems did not hold up in the desert heat, with parts overheating during recent testing. The US Army put its prototype command-and-control system to the test in the desert. Now, it's sorting out what performed well enough to be scaled across the service — and what should be cut. The Army has been developing Next Generation Command and Control , or NGC2, alongside industry partners like Anduril and Palantir, and at a recent exercise at Fort Irwin, California, the service put it to work in a large-scale desert combat scenario.
