Commando: Britain's Ocean Warriors

Sunday, 8pm, BBC2

If you thought SAS: Who Dares Wins was tough, then BBC2's new four-part series Commando: Britain's Ocean Warriors is a real eye-opener.

It follows the inside story of the Royal Marines Commandos, Britain's elite fighting force, as they're deployed anywhere in the world at a moment's notice, acting as strike troops, peacekeepers and seaborne raiders.

Undertaking dangerous tasks

But the road to becoming a commando begins with the longest infantry training in the world and only a select few are good enough to wear the coveted green beret. Every year, 26,000 hopefuls apply, but just 400 make it.
