Image caption, The call from Ukraine for more weapons and ammunition to bolster its defences has grown louder as the war has gone on
A year ago Volodymyr and his men were firing all 40 barrels of their BM-21 Grad rocket launcher in one go. Now they can only afford to fire a few at a time at Russian targets.
“We haven’t got enough ammunition for our weapon,” he explains.
His unit, the 17th Tank Battalion, is still being called on to provide fire support to Ukrainian forces desperately clinging on to the edges of Bakhmut, the eastern Ukrainian city which Russia has spent months trying to capture.
Russian forces are getting ever closer to their goal of taking the city but at an enormous cost.

His men remove the branches camouflaging their vehicle. They drive towards an empty field about a kilometer away and quickly work out the range.
They’re told their first rocket misses by about 50 meters, so they adjust the elevation and fire another two, and quickly return to the trees for cover. This time they’re told they’ve hit the target.
Volodymyr however, is frustrated they can’t do more. “We could have provided more support to our guys who are dying there.”
He says Ukraine has already burned through its own stocks of Grad ammunition, so is relying on rockets sourced from other countries. Volodymyr says supplies are coming from the Czech Republic, Romania, and Pakistan. He complains the rockets originating from Pakistan are “not of a good quality”.

Ukraine’s call for more weapons and ammunition has only become louder the longer the war has gone on. The focus now is preparing for a major offensive. But at the same time, Ukraine is still having to expend huge resources on just maintaining its position.
Despite the recent arrival of modern weapons – like tanks and armored vehicles – Ukraine remains heavily reliant on its older, Soviet-era arsenal.
This sophisticated weaponry has helped prevent Russia from gaining control of the skies.
Josef, the Buk commander, tells me it’s “target number one for Russia”. This explains the extreme care taken to protect it. The long vehicle with its radar dome is buried in a deep trench covered with camouflage netting. On top are two grey missiles. Normally it carries four.

A cache of classified US documents was leaked online earlier this month – maps, charts, and photos – revealing detailed intelligence gathered on the war.
I ask Josef if these were correct in highlighting an acute shortage of Buk missiles. “No, that’s not true,” he insists. But he does admit that the Buk is proving hard to maintain and Ukraine needs more.
“We haven’t got enough,” he says. “Parts break and we haven’t got spares because the factories that produce them are not in Ukraine.”
“Why should we be angry with the Americans?” he asks. “Because they gave information the Russians have had for 20 years? Ridiculous!” Russia, he believes, has always known about the capabilities of Ukraine’s armed forces.
But Russia still does not know the timing or place of Ukraine’s expected offensive. It will be key to taking back territory and relieving some of the pressure being felt along Ukraine’s 800-mile (1,300km) front. Wherever it happens Russia will have to redirect some of its forces.
But Ukraine too is having to arm and equip new units to conduct that offensive. Both sides are struggling to feed the front line.
We’re worried our Western allies are getting tired of helping us
At another location near Bakhmut, Ukrainian troops from its 80th Brigade are already expending hundreds of artillery rounds a day, to try to repel Russia’s advances.
They are already using some of the weapons supplied by the West. Serhiy and his men are operating a British-made L119 light artillery gun. But Serhiy says they too are having to ration rounds. He says they’re firing on average 30 rounds a day.
“We’ve got enough people for the moment”, he says. “But we need ammunition. Ammunition is the most important.”
I ask Serhiy if this is the make-or-break year for Ukraine. “If we go on the offensive this year and retake our land, then we’ll win,” he replies. “But, if that doesn’t happen, then we don’t have the resources for the war to go on for another five to ten years.”
Volodymyr, the commander of the Grad, is even more blunt. “The country is exhausted, the economy too,” he says.
And he fears that if Ukraine’s actions on the battlefield are not decisive this year then Western support may falter. “We are also worried our Western allies are getting tired of helping us.”
