Singh visited the 'war room' of the Directorate of Military Operations where he was given a detailed briefing on the preparedness of the armed forces, Defence Ministry officials said here.
The Prime Minister was briefed about the situation along both the eastern and the western borders and the operational readiness of the armed forces there, they said.
The Prime Minister addresses the top tri-services brass at the Combined Commanders' Conference annually but rarely comes to the Army Headquarters for such briefings, sources said.
The armed forces are also gearing up for enhancing security preparedness in the backdrop of the US pull out from Afghanisatn after which it is being feared that terror elements will spread out in the region creating problems for countries such as India.
