Ukraine's war machine is starting to slow down as Western ammo dries up

• A top Ukrainian commander says its forces are having to scale back military operations.
• Troops are facing ammo shortages "across the front line," he said.
• Kyiv's forces have relied on Western aid to power its war machine — and that aid is running out.

With Western countries holding back on sending more military aid to Ukraine, Kyiv's forces are running out of ammo.

That's forcing Ukrainian troops to start cutting back on military operations and going on the defensive against Russia, according to a top military commander.
