CAMP ATTERBURY, Ind. (Feb. 5, 2019) — From Eastern Europe to across the United States, paratroopers with 1-508th Parachute Infantry Regiment (PIR), 82nd Airborne Division (Airborne) are assessing a new concept that is transforming the Army’s tactical network.
Known as the Integrated Tactical Network (ITN), the new approach provides smaller, lighter, faster and more flexible communications systems with multiple connectivity options that are available primarily at the battalion and below level, down to the dismounted Soldier.
… The Android Tactical Assault Kit (ATAK), which is an unclassified version of the Nett Warrior hand-held situational device, is another lightweight ITN component. Sgt. 1st Class Arbie Ignatius Melendrez is the 1-508 PIR battalion fire support non-commissioned officer. He is responsible for integrating and coordinating all fires support within the battalion, and stated that the ATAK is benefitting all of the company forward observers and fire support officer.
