Network Centric Operations (NCO) is a term used in military activity. It describes the provision of robustly networked, collaborative armed forces capabilities. NCO covers the complete command, control, and communication infrastructure. The objective is to enable soldiers, commanders, and equipment to have immediate secure controlled access to every relevant asset. Real-time information sharing across surveillance systems, and land, sea & air weapons, integrated with command-and-control IT systems is needed to implement NCO.
