The UK's military role in Afghanistan began in 2001, in the wake of the 9/11 attacks on the World Trade Center in New York.
For more than 14 years, the role of British forces in Afghanistan dominated front-page news.
Four hundred and fifty-four British military personnel died from injuries or illnesses sustained during involvement in the UK's combat operation.
Although British forces left their combat role in Afghanistan, known as Operation Herrick, on 27 October 2014, troops remain in the country in non-combat capacities.
Framed by the high mountains of the Hindu Kush sits Kabul, the Afghan capital.
It was once a key stop on the silk routes of Asia - a place full of gardens, bazaars and grand palaces, however, today it is regarded as one of the most dangerous cities in the world.
In the capital, there is a major NATO effort to try and provide some stability, with British forces playing a leading role.
Around 1,000 UK troops are deployed to Afghanistan, as part of Operation Toral - Britain's contribution to the NATO Resolute Support mission.
Troops have three main non-combat roles - the first is as 'Guardian Angels', which sees soldiers provide security and protection to NATO advisors and government officials.
British forces are tasked with transporting and accompanying government officials across the capital and beyond.
Soldiers drive dignitaries around in the Foxhound armoured vehicle, amid the threat of suicide bombers and improvised explosive devices (IEDs).
Aircraft from the Royal Air Force have also been used to transport officials.
The Taliban, Al-Qaeda and so-called Islamic State (IS) are just some of the threats which face British personnel and NATO allies in Kabul.

British soldiers in Afghanistan have also formed part of NATO's Quick Reaction Force, which responds to emergency situations across the capital.
Troops are held on standby 24/7 and are given five minutes' notice to react to an emergency, whether it is a fire or an attack.
In January 2018, soldiers from 2nd Battalion The Yorkshire Regiment were called into action.
They helped evacuate civilians from Kabul's Intercontinental Hotel after an attack by the Taliban.
Twenty-two people were killed during the 13-hour siege but 2 YORKS, alongside their Afghan, Australian and US counterparts, helped rescue 43 people.
'Sandhurst In The Sand'
UK military personnel are also helping to train the next generation of Afghan Security Forces soldiers.
In 2013, Britain helped establish the Afghan National Army Officer Academy, also referred to as 'ANAOA', in the western outskirts of Kabul.
Modelled on Sandhurst, and built with £75m of British money, everything on the curriculum is influenced by UK military training.
British troops do not teach the troops directly, but rather mentor the instructors.
ANAOA takes its core principles from the British Army and there are aspirations it will reach the same level of academes in India and Pakistan.
The long-term plan is for a gradual drawdown of NATO mentors by 2026.
It is hoped what they leave behind is a first-class training academy, able to produce leaders in the Afghan Army.
There have been signs of war coming to end in Afghanistan, however, peace still seems a long way off.
At the beginning of September, a US envoy to Afghanistan said a peace deal with the Taliban had been agreed "in principle".
However, days later the deal was called off by President Donald Trump after a Taliban car bomb close to the NATO Resolute Support mission HQ killed an American soldier.
British soldiers were said to be at the scene retrieving what appeared to be the remains of a NATO vehicle.
Mr Trump said the peace negotiations were "dead" but last week, the US Defense Secretary visited Afghanistan to try and revive a deal.
Mark Esper said: "The aim is to still get a peace agreement at some point."
The previous deal would have seen more than 5,000 American troops withdraw from Afghanistan over a five-month period.
Earlier this year, the chair of the Defence Select Committee in the UK said it was "fanciful" to believe British forces could stay in Afghanistan if the US withdraws.
The majority of western combat forces, including the UK, left Afghanistan in 2014.
Meanwhile, the US continues to combat operations in the country as it looks to end its longest-ever war.
For the UK, its future in Afghanistan looks fairly certain.
In January, a senior British Army officer said there are no plans for a British drawdown.
Last year, then-Prime Minister Theresa May announced Britain was sending an extra 440 troops to the country - taking Britain's number of troops in the country to 1,090.
That number is twice the amount the UK had when it ended combat operations five years ago.
At the height of the Afghan war, NATO had more than 130,000 troops from 50 nations in Afghanistan - the UK had 9,500 personnel.
