Nine members of the Czech Republic's most prestigious army unit, the Castle Guards, are facing disciplinary action after it emerged that they took part in a photo shoot for a gay porn Website.

Jaroslav Pekar, head of the Castle Guard, said that he accepted the soldiers had not meant to embarrass the unit in any way but that they will be punished. This could mean that they are demoted or jailed for one week.

The soldiers were paid approximately $20 for each picture in which they stripped to their underwear.

The guard who suggested the idea to his peers has already resigned.
