Missiles from the West for Ukraine

What difference will long-range missiles from the West make for Ukraine?

Russian missiles struck the Ukrainian capital Kyiv on Sunday for the first time in a month.  The country’s railway operator says one of its facilities was hit.  Russia claims it was targetting western-donated tanks.  The attack came as President Volodymyr Zelenskyy visited troops and towns in the eastern Donbas region.
