PRINCE William was taught to use to a sub machine-gun and other firearms as part of a survival training lesson with the SAS in Hereford.

He wore protective body armour and goggles as he was put through his paces at the Stirling Lines camp in Hereford, according to a national newspaper report.

The intensive training day took place in August, 1998, when William was 16, and was organised by his uncle, Lord Spencer.

During the intensive training session, the Prince was given a detailed safety briefing before being handed a loaded weapon.

He also had to undergo a mock ambush and was bundled into a getaway car as shots flew around him.

"He had a fantastic day and really enjoyed himself," a former SAS trooper, who witnessed the event, told the paper.

"But there was a serious side as he took part in the mock ambush and learned what to do."

A spokeswoman for Prince William said this was a "private visit some years ago".
