G2 is the staff appointment within NATO for officers who provide timely, relevant, accurate, and synchronized intelligence about the enemy from a wide range of sources and sensors for tactical, operational and strategic-level commanders.
The end of the Cold War and the changing character of the threat to national and international security has broadened the scope of intelligence. It is now a multi-agency function that embraces not only the Armed Forces, but Police and Customs and Immigration as well as national counter intelligence and terrorism organisations like MI5, and the FBI. Just as crucial are the intelligence collecting agencies like GCHG, the CIA and MI6 that can allow the plans and plots of hostile groups to be monitored and neutralised.
The threat is global - the terrorists who have targeted the United States and Europe had received their training in Afghanistan and Pakistan. Modern communications allow images, information and ideas to be transmitted in seconds around the world. Just as the threat is global - so too is the need for accurate and timely intelligence that is speedily disseminated.
