FORT DRUM, N.Y. -- A rainbow across the sky at Fort Drum’s live-fire range August 22 spans the training site of Soldiers from the 1-258th Field Artillery annual training. In the foreground are vehicles from the 27th Brigade Special Troops Battalion (BSTB) communications team. The brigade Soldiers were on site to train leaders, staff and operators on the Joint Network Node (JNN) system of digital communications. The JNN package is very mobile and designed to provide communication services to the battalion command posts up to the brigade combat team. Photo by Sgt.
