Ukrainians on the front line believe they "need" vast numbers of Western tanks to win the war against Russia.
Ukraine needs Western tanks
The UK and other European nations are preparing to send armoured machines to help the country liberate more territory and those currently battling Vladimir Putin's troops admitted they are much needed because their own vehicles are so old.
Bogdan, a 55-year-old Ukrainian volunteer said: "T-72s are old tanks - this one's the same age as me.
"I used to drive one of these nearly 40 years ago - I can't believe I'm doing it again. But it works. It does the job."
A fellow crew member, Volodymyr added: "But a Leopard would be better."
Danylo, an officer in charge of repairing tanks, said significant numbers of foreign tanks are needed.
He said: "We'll be stuck here. We need these [Western tanks] to stop Russia's aggression. With infantry, covered by tanks, we'll win for sure."
Bogdan added to the BBC: "Leopards, Challengers, Abrams - any foreign tank is good for us! I think we need at least 300. And we need them now
"The Russian tanks are a bit better than ours. They're fully modernised. But mostly the Russians are strong because they push forwards en masse, advancing over the bodies of their own soldiers. Our commanders care more about the lives of their crews, so we try to destroy [the enemy] while losing as few of our own men as possible."
