Providing aid to a fictional village after a hurricane is among the tasks faced by recruits at HMS Raleigh as they complete the final exercise of their training.

Sent to help a community struck by a hurricane, the recruits are set to work to establish headquarters and form working parties to scan the area for casualties and other hazards.

The tasks include rescuing injured survivors from a downed helicopter and carrying them back to the first-aid tent, but first they must build a bridge to carry the casualties over water contaminated by toxins.

They also need to be aware of rebel forces in the area and take the right precautions to maintain their own safety and the safety of the community.

The exercise, known as Bright Diamond, sees the classes acting as the crew of the training ship Brecon, moored on the River Lynher.

The recruits stay on board Brecon for part of the three-day exercise, following the routines they would at sea such as keeping watches and taking part in flood and fire exercises.

They also take part in navigation exercises on the Rivers Lynher and Tamar, driving the small boats and plotting their course.

Initial naval training at HMS Raleigh is 10 weeks long and designed to teach the recruits the basic skills they will rely upon throughout their careers.
