President Biden announced Wednesday that his administration would send Ukraine $800 million in additional military aid, including heavy weapons and helicopters, as the embattled nation braces for renewed fighting in the east.

The package, revealed after an hour-long phone call between Biden and Ukrainian President Volodymyr Zelensky, includes 11 Soviet-made Mi-17 choppers — originally meant for the Afghan army — that can be used as transports or gunships.

Fox News had reported earlier Wednesday that the US had backed out of initial plans to furnish Ukraine with the Mi-17s. White House press secretary Jen Psaki claimed at her briefing Wednesday that confusion on the Ukrainians’ part was to blame for the snafu. 

“It was unclear for a while from their side whether they wanted additional helicopters,” she said. “We have provided them helicopters in the past, and today they made clear they wanted them in, so we said ‘Great.’

The aid also includes:

The package also includes more Javelin missiles and Switchblade drones, as well as an assortment of protective gear and explosives.

The 11 Mi-17s will join five other such helicopters that were transferred to Ukraine earlier this year, according to the Pentagon.

The shipment comes as Russia is repositioning its troops to move on the eastern Donbas region of Ukraine, where sporadic fighting has taken place since Russia backed a separatist movement in the region in 2014. 

“[Ukrainian troops] will be facing Russian forces that are familiar with the territory in that part of Ukraine. They’ve been fighting over it for eight years,” Pentagon spokesman John Kirby said. 

Kirby added Russian troops that had been pulled back from Kyiv for resupply were starting to be redeployed north of the Donbass region and said the geography of the region would be pivotal in the coming fight. 

“You’re looking at short supply route lines for the Russians because the Donbas region borders right up alongside Russia,” he said. “It’s the kind of place where we can anticipate the Russians will want to use tanks and long range fires — artillery and rocket fire — to achieve some of their objectives before committing ground troops.”

Earlier Wednesday, Zelensky had posted a list of requested weapons to social media Wednesday.

“We urgently need heavy artillery, heavy armored vehicles, air defense systems and aircraft,” Zelensky posted to his official Telegram channel.

“To continue heroically defending the world from Russian aggression, Ukraine needs a specific list of weapons,” his message read. “I appeal to citizens of the whole world to help convey to your governments, presidential administrations, and leaders of your countries the real needs of Ukraine, which will help stop the war.”

Zelensky’s wish list included heavy artillery pieces and armored personnel carriers like the ones the Biden promised, as well as rocket artillery, tanks, and combat aircraft.

“The steady supply of weapons the United States and its allies and partners have provided to Ukraine has been critical in sustaining its fight against the Russian invasion,” Biden said. “It has helped ensure that [Vladimir] Putin failed in his initial war aims to conquer and control Ukraine. We cannot rest now.”
