Royal Marines from 45 Commando are training ahead of a potential deployment to provide humanitarian relief during the Caribbean's hurricane season.
The unit is being put on high readiness to respond and assist in the region over the next few months.
They are training with the kit they will be using to help save lives and rebuild communities devastated by any natural disaster.
"We're at readiness for lots of different environments," Major Josh McCreton, Officer Commanding Zulu Company, said.
"But bringing in these particular skills - where they can operate specialist power tools [and] specialist life-saving equipment is really important.
"The kind of challenges we're likely to face in the Caribbean are pretty extreme and it's really crucial that we can get there in those first couple of days and provide that life-saving support."
For some of them, it is the first time they have got their hands on this kind of equipment and they are learning how to use special tools to rescue casualties trapped in cars.
The aim is to get every member of 45 Commando up to speed in using everything they need if they deploy in the aftermath of a hurricane.
"It's all about professionalism," Marine Sam Hallidey said.
"If we go out there knowing exactly what we can do, that makes life a hell of a lot easier for us.
"Plus, for our allies in the Overseas Territories, we can potentially save lives."
The drills they are undertaking aim to ensure that 45 Commando are fully prepared to help rebuild areas and ensure the communities affected have the vital support they need to recover.
"It gives us a bit more confidence, especially younger lads who maybe haven't done anything like this before," Corporal Connor Fairley said.
45 Commando will be primed to deploy within days in the event of any hurricane between now and November, ready to deliver the urgent life-saving help to any community in need.
Meanwhile, HMS Medway and RFA Argus are already in the Caribbean ahead of hurricane season, ready to react to natural disasters and carry out counter-narcotics operations.
They have recently come together for the first time during disaster relief exercises in the Cayman Islands, aiming to demonstrate the Royal Navy task group's ability to work together during a crisis.
During their stop on the Caymans, they delivered what is known as the Humanitarian Assistance Disaster Relief Capability (HADR).
The task group also worked on practising the evacuation of casualties to the ships.
