Short on ammo, Ukrainian artillerymen can't fire on a hunch anymore. They have to know the Russians are there.

• Russia is exploiting Ukraine's increasing artillery shortage as it ramps up attacks.
• Ukraine is firing just 2,000 rounds a day compared to Russia's 10,000 shells.
• The ammo shortage means Ukraine is being forced to prioritize its targets more carefully. 

Ukraine's increasing ammunition struggles have hamstrung its war effort, forcing the country to sacrifice long-term strategy for short-term certainty.
