Exercise Shamal Storm will see 1,600 troops deploy to Jordan alongside a wide variety of units from Force Troops Command and 3 [UK] Division. 
The Army are determined to show they are still capable of deploying a 30,000-strong force to a crisis zone anywhere in the world.
An Army spokesperson said:
"The exercise in Jordan presents the British Army with a challenging environment in which to assure its combat readiness to deploy and support an armoured force of up to 30,000 troops anywhere in the world."

The bilateral exercise, named Shamal Storm for the wind storms that occur in the Jordanian desert, has been held for many years, but this occasion will see a significant increase in troop numbers.
Army sources dismissed speculation that despite being held in Jordan, a region that borders war-torn Syria, the exercise was not a dress rehearsal for any British-led campaign against ISIS.
A source told The Telegraph:
“This isn’t a counter-Isil exercise. If anything, this is much more about us being prepared to join the US in Ukraine than it is in Syria."
“This is not the sort of kind of force you expect to roll into Aleppo to take on a bunch of jihadists.”
Recent conflicts in Afghan and Iraqi theatres were focused on counter-insurgency, rather than any large scale conflict. It is this disparity the Army is trying to redress.
"The exercise will test key concepts such as the air deployment of a very high readiness field hospital and the latest explosives ordnance disposal and search capabilities, all of which will enable us to be more agile in deterring threats to the UK and its interests.
