Ammunition arithmetic at Avdiivka
Published 6 October 2026
The US funding bottleneck was visible before Avdiivka's final battle. On 2 October 2023, Reuters reported that the shutdown-averting spending agreement excluded further Ukraine aid. A US official put remaining Defence Department replacement funding at $1.6 billion, new Ukraine Security Assistance Initiative funding at zero, and unused Presidential Drawdown Authority at $5.4 billion. Those are different authorities: permission to transfer existing weapons could remain while money to replace them dwindled. The report therefore supports a constrained funding pipeline from autumn 2023, not the claim that every American shipment stopped on 1 October.
The final withdrawal from Avdiivka was preceded by a sequence of smaller movements. On Thursday, 15 February 2024, military spokesman Dmytro Lykhoviy told Reuters that Ukrainian units were pulling back to more advantageous positions in some parts of the town while trying to push Russian troops out of others. The Third Assault Brigade had been rushed in to reinforce the defenders. Its deputy commander Maksym Zhorin described the fighting as fiercer than Bakhmut and said Ukrainian forces were outnumbered and outgunned. Lykhoviy put the Russian force on the Avdiivka front at around 50,000 troops. That was a Ukrainian military estimate reported by Reuters, not an independently verified Russian deployment count.

On Friday, 16 February 2024, commander Oleksandr Tarnavskyi said Ukrainian troops had left the Zenit fortified area in the southeast of the city. He described the remaining position as ruins and broken bricks and said saving soldiers' lives was the priority. He also said Russian forces were bombing day and night and attacking from several directions. Later that day he claimed Ukrainian troops had repelled more than 30 Russian attacks while continuing their defensive operation. These statements document the command's account of a collapsing position, not an audited battlefield casualty ledger. Keeping them attached to Tarnavskyi prevents the report from quietly converting one side's operational claims into independent findings.

Ukraine pulled its troops out of Avdiivka on Saturday, 17 February 2024. Reuters' report, updated the next day, described Russia's subsequent claim of full control and Ukraine's explanation that withdrawal was necessary to avoid encirclement and preserve troops. The fall was Russia's biggest gain since Bakhmut in May 2023. Avdiivka had been contested and fortified over years. Its loss belonged to a long conflict, not a town's sudden appearance on a strategic map.
The broader problem was documented in Reuters's Wednesday, 21 February 2024 field report, based on interviews with more than 20 soldiers and commanders across infantry, drone and artillery units along the eastern and southern fronts. A Third Assault Brigade spokesperson said the Avdiivka defenders had been outnumbered seven to one. A commander in the 59 th Brigade estimated that 60-70 percent of the several thousand men in his brigade at the war's start were still serving; the remainder included men killed, wounded or discharged because of age or illness. Those figures describe different units and different measures. (Reuters, Ukraine outnumbered, outgunned, ground down by relentless Russia, 21 February 2024)
The same report found ammunition and rotation problems rather than one single cause of the defeat. A GRAD rocket-artillery soldier said his launcher was operating at roughly 30 percent of maximum capacity; a company commander described ordinary respiratory illnesses taking exhausted soldiers out of action when no replacements were available. Reuters reported that the EU expected to miss its target of supplying a million artillery shells by March 2024 by nearly half, while US assistance was stalled. These observations give Avdiivka a material context: a defended city could be lost through the interaction of manpower, firepower, medical absences and the inability to rotate troops. The 30 percent figure remains the account of one launcher operator, not a national artillery utilisation statistic. (Reuters, 21 February 2024 field report)
The eventual legislative sequence came too late to affect Avdiivka's February withdrawal. The House approved the foreign-assistance measures on Saturday, 20 April 2024; the Senate followed on Tuesday, 23 April, by 79 votes to 18. Reuters's 23 April dateline, updated 24 April, reported the roughly $61 billion Ukraine component alongside separate Israel and Indo-Pacific measures. The Senate vote authorised a new funding channel after months of delay, but was not itself a delivery to Ukrainian units.
After Biden signed the legislation on Wednesday, 24 April, he approved an initial $1 billion weapons package and said shipments would begin within hours. Reuters listed Stinger air-defence munitions, 155 millimetre artillery ammunition, HIMARS ammunition, TOW and Javelin anti-tank weapons and vehicles. This inventory is more informative than a generic declaration that "aid returned": it identifies the air defence, artillery and ground-combat supplies Washington selected for immediate movement. It does not establish when every item reached a particular brigade or that all shortages disappeared that week. The signature, drawdown announcement, dispatch and front-line availability remain different steps.
Zelenskyy's 24 April response called the congressional delay half a year lost and named the incoming weapons he considered necessary: ATACMS, artillery, anti-tank weapons, HIMARS and air defence. The statement supplies Ukraine's contemporaneous assessment of the shortfall rather than a retrospective casualty calculation. It belongs beside the earlier evidence of shell shortages, but should not duplicate the round 1 seven-to-one manpower claim or convert the delay into a numerical death toll unsupported by this source.
