A fleet of drones made out of cardboard and held together with elastic bands and tape are thought to have destroyed or damaged at least five Russian jets in the Ukraine war.

A sniper rifle has proven so effective on the battlefield in Ukraine that it has become highly sought after by soldiers on both sides of the conflict. The Ukrainian military claims the UAR-10 can hit targets 1,200 metres away – more than the 800-metre range of the Russian Dragunov or SVD the Ukrainians were using previously.

Camp Bastion opened in 2007 and was once the largest British overseas military base on the planet, home to 114,000 personnel. Four years after UK troops left and it was handed back to the Afghan Army, I gained exclusive access, the last British journalist to see a place so many once called home.

As Iraqi forces fought their way into Mosul, they received air support from a coalition of nations. Among the largest contributors was France. The French aircraft carrier Charles De Gaulle operated from the Eastern Mediterranean and was the only European aircraft carrier involved in Operation Inherent Resolve. We spent three days on board meeting the crew, and the pilots flying dangerous missions as part of Operation Chamal.

The senior officer who came up with the UK military’s strategy on climate change and sustainability visited Antarctica to see the growing effects of global warming. I travelled with Lieutenant General Richard Nugee on his 9,000-mile trip, hearing his thoughts on why defence, like every sector of the UK, needs to cut emissions and embrace new greener sources of energy.

It's stood abandoned for more than four decades, and to step inside its once gleaming terminal building is to step back in time. Nicosia International Airport is perhaps one of the most evocative symbols of the nearly 50 year division of Cyprus. This was a rare chance to look inside.

As the former Afghan government made a last-ditch push for peace with the Taliban, we travelled to Kabul to film British troops as they dealt with a wave of suicide bombings.

Ukrainian soldiers have been seen using the two-metre-long Alligator anti-materiel rifle. The 25kg weapon is designed to eliminate vehicles, not people.

Operation Shader began as a humanitarian aid mission but grew into a complicated mission to try and defeat the Islamic State. Since 2014, RAF aircrew based in Cyprus have been flying daily missions over Iraq and Syria as part of a coalition of nations. Keeping them flying are the RAF's fleet of Voyager tankers.
