In 2006 thousands of UK nationals were evacuated from Beirut when war broke out between Hezbollah and Israeli forces.
Second Battalion the Royal Anglian Regiment on Exercise Turbulent have shown Forces News how they practise dealing with such an evacuation.
Over the course of the exercise, troops were tested on how they deal with a whole range of scenarios- including processing evacuees fleeing a pretend conflict, as Lieutenant Colonel Bruce Weston told us:
"At the reception centre, troops would receive a brief from the foreign and commonwealth office, who take the lead in this type of operation".
And it wasn’t long until the first test came - two injured men were brought to the reception centre.
It soon emerged that one didn’t have a passport and while the troops provided first aid, they also had to try and work out who he was.
The UK military faced these sort of challenges for real in 2006 during Operation Highbrow, when Hezbollah and Israeli forces clashed in southern Lebanon.
Four and a half thousand British Nationals were eventually evacuated aboard Royal Navy warships, first to Cyprus, then back to the UK.
Since last summer the Poachers have been the UK’s Regional Standby Battalion for the Middle East and North Africa.
It means that should that happen again, it would be these soldiers who were sent.
For the men of A Company, this training is all part of their current role as the Poacher’s lead unit-the first to deploy.
For all the soldiers taking part, there have been lessons learned, making sure they’re ready should they have to do it for real.
