Machine guns rattle from the rooftops as troops duck and weave below.

At an undisclosed location in East Anglia, the Ukrainian army's newest recruits are defending a mock village from attacking British infantry.

Members of the media were allowed to observe the exercise on condition they did not reveal its location for security reasons.

Just days from now, they almost certainly will do. And by then the bullets will be for real.

And their mentors from British regiments, along with elements of the Swedish, Finnish, Danish and Romanian armies, hope the skills they have learned will boost their chances of surviving to see victory.

"In the beginning it was really hard because I had just come from civilian life," he said.

"I haven't been home for a long time, but in a couple of days we're going to go back and there's a war.

"I'm worried but I want to go back, I want to win the war obviously. I know we're going to win this war."

"It's good training, we've had a lot of scenarios," he said.

"It's a very good experience before we start fighting in real life. It won't be something we fear now, it's not going to give us stress."

"The invasion by Putin was illegal and Britain is really clear it will support Ukraine and do everything it can."

After the guns fall silent, Ukrainians gather on a makeshift parade ground and stand to attention for Shche ne vmerla Ukraina, their national anthem: Ukraine has not yet perished.

"This is an intimate moment between soldiers," barks a British officer before the song begins.

Equipping Ukraine's volunteers with fighting skills and kit

More than 23,000 recruits from the Armed Forces of Ukraine have already received training in the UK since the start of 2022.

Each undergoes five weeks' training including trench and urban warfare, the law of armed conflict, battlefield first aid, counter drone measures and cyber warfare.

They aim to give volunteers with little to no military experience the skills to be effective in frontline combat including handling weapons, battlefield first aid, fieldcraft and patrol tactics.

In just days from now, they will be facing Russia's armed forces.
