The Russians have the same type of ammo.

The Russians have overwhelming military force in Ukraine. The West cannot give Ukraine enough of anything to make a difference in the outcome of the war.

The West are scraping the bottom of the barrel to give any more weaponry to Ukraine. The numbers of tanks are meagre. The numbers of artillery shells dwindle with each promise to Ukraine.

Ukraine is running out of ammo and running out of soldiers. They're conscripting children now for God's sake.

Ukraine is Dead Man Walking.
