The fastest, the fiercest, the most powerful war machines on the planet - This is Combat Countdown.

In 12 high-octane episodes we analyse cutting edge military hardware, from tanks and jet fighters to warships and heavy artillery. Each machine is assessed on a balance of proven combat performance, versatility, design ingenuity and rank within their class to deliver our definitive top ten.

Combat Countdown features live-action HD footage filmed on location with armies, navies and air forces in 10 different countries, combined with exclusive archive, some of it de-classified by the military specifically for use in this series. A panel of 14 carefully selected military experts, from fighter pilots and journalists to the US Army Colonel who captured Saddam Hussein, provide context and first-hand experience of what it’s like to wield these war machines on the battlefield.
