Brunei has a long relationship with the British Armed Forces.
Swapping military vehicles for jungle boots and strong backs it has often proved the ultimate training ground for jungle warfare, with troops learning to live, survive and fight in a unique environment.
Currently enjoying the oppressive heat and cloying humidity are Y Company, 1st Battalion Regiment of Royal Fusiliers (RRF), normally based at Tidworth in Wiltshire.

The Fusiliers, who are usually an armoured infantry unit using the Warrior fighting vehicle, have relished the opportunity to re-engage with the light infantry role.
They have been training hard, in their core skills; ranging from basic field craft to more advanced jungle survival techniques. But working in such hostile conditions brings a host of new challenges which the Fusiliers have had to learn to overcome.
Lance Corporal Daniel Teesdale said: "Navigating out here is a massive challenge, usually you can see a good kilometre away, and can have a good view of key landmarks, in the jungle you can barely see 20 meters ahead of you, and it can take 20 minutes to go just 100 meters as you hack your way through the undergrowth."

The troops will be living in the jungle for the next month, training in heat that has exceeded 35 degrees. Learning to use their environment to their advantage and prove why the British army is such an effective, adaptable fighting force - able to deploy and operate anywhere in the world.

Major Alex Mills, Officer Commanding Y Company RRF said:"This is a once in a generation opportunity for my guys. The experience we have gained out here has been invaluable. It's been hard work, but the guys have relished the opportunity to learn the techniques to operate, survive and fight in this unforgiving terrain."
