The Biden administration said it would send weapons to Ukraine as part of an additional $800 million aid package as the country prepares to combat increased Russian aggression in the east.

The White House said in a Wednesday press release that the new package will include many of the highly effective weapons systems the US has already provided to Ukraine.

President Joe Biden said he approved the transfer of additional helicopters.

John Kirby gave a full rundown of what is included in the aid during the Pentagon press briefing.

The package includes chemical, biological, radiological, and nuclear protective equipment after the Pentagon said it was closely monitoring claims that Russia used chemical weapons in the besieged Ukrainian city of Mariupol.

Some of the new capabilities, including the planned transfer of Howitzer cannons, will require training for Ukrainians to use them in a scenario that will likely see the US teach a small number of Ukrainian troops how to use the equipment.

The State Department said last week that the US had provided more than $2 billion in military assistance to Ukraine since Biden took office.

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, according to the White House press release.
