Squads and above at an 82nd Airborne Division prototype brigade will start training with gear from the Army’s integrated tactical network this winter.
The gear will include lighter and faster communication equipment, battle-tracking applications on tablets and new ways to communicate with one another, as well as partner forces. By using a secure-but-unclassified architecture, soldiers can tap into commercial cellular networks, like 4G, and a greater range of wavelengths, depending on the electronic threat environment.
