What’s the Story of the “Nuclear Football” That Always Goes With the President?

From an AP story by Del Quentin Wilber headlined ‘You always hear about the ‘nuclear football.’ Here’s the behind-the-scenes story”:

The most important — and mysterious — “football” in the world isn’t a football at all.

Officially called the “ Presidential Emergency Satchel, ” the “nuclear football” is a bulky briefcase that contains atomic war plans and enables the president to transmit nuclear orders to the Pentagon. The heavy case is carried by a military officer who is never far behind the president, whether the commander-in-chief is boarding a helicopter or exiting meetings with world leaders.
