BBC Defence correspondent, Bakhmut
A twelvemonth agone Volodymyr and his men were firing each 40 barrels of their BM-21 Grad rocket launcher successful 1 go. Now they tin lone spend to occurrence a fewer astatine a clip astatine Russian targets.
"We haven't got capable ammunition for our weapon," helium explains.
His unit, the 17th Tank Battalion, is inactive being called connected to supply occurrence enactment to Ukrainian forces desperately clinging connected to the edges of Bakhmut, the eastbound Ukrainian metropolis which Russia has spent months trying to capture.
Russian forces are getting ever person to their extremity of taking the city, but astatine tremendous cost.
While we're waiting successful a enactment of trees, hidden from view, Volodymyr receives a telephone to occurrence his rocket launcher astatine a Russian mortar presumption astir 15 kilometres away.
His men region the branches camouflaging their vehicle. They thrust towards an bare tract astir a kilometre distant and rapidly enactment retired the range.
They elevate the rocket barrels towards the people while, retired of sight, a Ukrainian drone hovering supra assesses their accuracy.
They're told their archetypal rocket misses by astir 50 metres, truthful they set the elevation and occurrence different 2 and rapidly instrumentality to the trees for cover. This clip they're told they've deed the target.
Volodymyr however, is frustrated they can't bash more. "We could person provided much enactment to our guys who are dying there."
He says Ukraine has already burned done its ain stocks of Grad ammunition, truthful is relying connected rockets sourced from different countries. Volodymyr says supplies are coming from the Czech Republic, Romania and Pakistan. He complains the rockets originating from Pakistan are "not of a bully quality".
Ukraine's telephone for much weapons and ammunition has lone go louder the longer the warfare has gone on. The absorption present is preparing for a large offensive. But astatine the aforesaid clip Ukraine is inactive having to expend immense resources connected conscionable maintaining its position.
Despite the caller accomplishment of modern weapons - similar tanks and armoured vehicles - Ukraine remains heavy reliant connected its older, Soviet-era arsenal.
The Russian-made Buk aerial defence system, which tin people aircraft, drones and missiles, is inactive 1 of its prized possessions. We get uncommon entree to spot 1 further on the beforehand enactment - besides hidden successful a wooded area.
This blase weaponry has helped forestall Russia gaining power of the skies.
Josef, the Buk commander, tells maine it's "target fig 1 for Russia". This explains the utmost attraction taken to support it. The agelong conveyance with its radar dome is buried successful a heavy trench covered with camouflage netting. On apical are 2 grey missiles. Normally it carries four.
A cache of classified US documents was leaked online earlier this period - maps, charts and photos - revealing elaborate quality gathered connected the war.
I inquire Josef if these were close successful highlighting an acute shortage of Buk missiles. "No, that's not true," helium insists. But helium does admit that the Buk is proving hard to support and Ukraine needs more.
"We haven't got enough," helium says. "Parts interruption and we haven't got spares due to the fact that the factories that nutrient them are not successful Ukraine."
Josef doesn't lone quality immoderate of the contents of those leaked US quality reports. He questions whether they person truly revealed immoderate secrets.
"Why should we beryllium aggravated with the Americans?" helium asks. "Because they gave accusation the Russians person had for 20 years? Ridiculous!" Russia, helium believes, has ever known astir the capabilities of Ukraine's equipped forces.
But Russia inactive does not cognize the timing oregon spot of Ukraine's expected offensive. It volition beryllium cardinal to taking backmost territory and relieving immoderate of the unit being felt on Ukraine's 800 mile (1,300km) front. Wherever it happens Russia volition person to redirect immoderate of its forces.
But Ukraine excessively is having to limb and equip caller units to behaviour that offensive. Both sides are struggling to provender the beforehand line.

At different determination adjacent Bakhmut, Ukrainian troops from its 80th Brigade are already expending hundreds of artillery rounds a day, to effort to repel Russia's advances.
They are already utilizing immoderate of the weapons supplied by the West. Serhiy and his men are operating a British made L119 airy artillery gun. But Serhiy says they excessively are having to ration rounds. He says they're firing connected mean 30 rounds a day.
"We've got capable radical for the moment", helium says. "But we request ammunition. Ammunition is the astir important."
I inquire Serhiy if this is the marque oregon interruption twelvemonth for Ukraine. "If we spell connected the violative this twelvemonth and retake our land, past we'll win," helium replies. "But, if that doesn't happen, past we don't person the resources for the warfare to spell connected for different 5 to 10 years."
Volodymyr, the commandant of the Grad, is adjacent much blunt. "The state is exhausted, the system too," helium says.
And helium fears that if Ukraine's enactment connected the battlefield are not decisive this twelvemonth past Western enactment whitethorn falter. "We are besides disquieted our Western allies are getting bushed of helping us."
