Russia’s offensive in the Donbas region is making slow progress. Having rushed to launch the operation to avoid giving Ukraine time to bring up new weapons from the west, Russia has found that its depleted and exhausted units are unwilling and unable to assault Ukrainian positions without incurring unacceptable losses. The Russian army has, therefore, fallen back on the mass application of artillery, destroying village after village, which they occupy after Ukrainian units withdraw.
For the Ukrainian military, the current Russian tactics may be unsophisticated and nihilistic, but they are also dangerous. To stop the Russians from advancing, the Ukrainian armed forces must occupy the ground. This subjects their units to heavy bombardment, and is producing a steady accumulation of Ukrainian casualties. The Ukrainians are trying to limit the weight of Russian fire by raiding and striking the logistics supporting the Russian artillery.
