How do the British Army keep an armoured column moving?

Keeping an armoured column on the move is no easy task, as Russian tanks discovered when they got bogged down in failed attempts to capture Ukraine's capital Kyiv earlier this year.

The Queen's Royal Hussars, who have been taking part in an exercise in Poland with their Challenger 2 tanks, are trained to repair smaller jobs themselves.

However, for more complex issues, they send for the Royal Electrical and Mechanical Engineers (REME) and their mobile repair shop.

• British Army Challenger 2s display firepower alongside allies in Poland
• British Challenger 2 tanks stored at Sennelager head to Poland

In Poland and across Europe, Russia's invasion of Ukraine has forced militaries to reasses the importance of armour and what it takes to keep tanks rolling.

The ability to fix problems on the go, thanks to the support of REME gives the Queen’s Royal Hussars greater confidence and capability, even in challenging terrain.
