The unexpected moments came at the stalls of Tata, Mahindra and Wipro. Their involvement in the defense field is known, but it was still surprising to see.
Wipro, for example, was showcasing some kind of lever for mounting and elevating various systems - an odd product to associate with the company known for software.
In reverse, Tata, a company that is easily associated with steel and heavy machinery, dedicated most of its display for its software and optics division - showing things like night vision, radios, and smart tracking systems.
Unmanned airplanes are all the rage now and a few Indian models, though very small and limited in scope compared to American drones, were also up for show.
But mostly the Indians were here to buy.
