Getting people and equipment there is difficult, with all deliveries having to be flown or shipped in.
As a British Overseas Territory, the people of the islands rely on Britain to guarantee their security.
Tasked with this crucial job is the British Forces South Atlantic Islands (BFSAI), staffed by more than 1,000 personnel from all three services, which also protects South Georgia and the South Sandwich Islands.
After the end of the Falklands War in 1982, Britain invested heavily in the islands' defences, including constructing a new airfield at RAF Mount Pleasant, 27 miles (43 km) west of the capital, Stanley.
The base became fully operational in 1986 after being opened the previous year. Stationed there are the four Typhoon jets that provide air defence for the islands and surrounding territories.
There is also one A400M and one Voyager aircraft, which are used for heavy lifting, transport and air-to-air refuelling.

Ships can dock at RAF Mount Pleasant's port facility, Mare Harbour.
It is speculated that the Royal Navy also has Trafalgar and Astute-class nuclear submarines, armed with Tomahawk cruise missiles, which could potentially be deployed to the area - although the details of these deployments are classified.
The submarines can hit targets up to 1,500 miles (2,400 km) away, including those within an enemy country. Their capability was demonstrated during the Falklands War when HMS Conqueror sank the Argentine cruiser ARA General Belgrano.
Also integrated into the defence system for the islands is their part-time volunteer force, the Falkland Islands Defence Force (FIDF), a company-strength light infantry force.
The FIDF does not come under BFSAI command as they are a national defence force. However, the BFSAI support their training when requested.
The FIDF receives training from a Warrant Officer seconded from the Royal Marines and has been trained by the Royal Navy to operate the Oerlikon 20 mm cannon and to board vessels suspected of fishery poaching.
The unique location and the special relationship with the Falkland Islanders allows the BFSAI to train in a unique environment.
