From the ABC news report on this:

A technician in the Royal Navy has become the first serviceman in Britain’s armed forces to be officially recognised as a Satanist, the Defence Ministry said today.

Chris Cranmer, 24, has been given the go-ahead by his captain to perform Satanic rituals on board the HMS Cumberland and is reportedly lobbying his employers to register Satanism as an official religion in the armed forces.

I guess that will liven things up a bit on board.. Be a pain keeping all the goats under control though.
