Ukrainian soldiers fear Russian artillery shell supply is endless.

Front-line Ukrainian soldiers in the Donbas region say it seems like Russia has "unlimited" artillery shells to throw at them — while they remain worried about running out by the end of the year. New weapons from the US and NATO allies, like the Abrams tank, could change the tide of the war. The US and its allies announced earlier this year that they'd send modern Western tanks to Ukraine. Just this week, the White House and Pentagon said they'd fast-track the delivery of older M1A1 Abrams tanks to Ukraine in eight to 10 months.
