Ukraine's Deadly Arsenal: The Aging BM-21 Grad Rockets & Their Crucial Role in the Conflict

Despite Ukraine receiving thousands of Western weapons, at least two-thirds of Kyiv’s arsenal is Soviet-era, like the BM-21 Grad rocket launcher. The Grad is falling apart and has no precision, but it can launch forty unguided rockets in twenty seconds, covering an area almost as large as ten football fields.

With their rocket supply running thinner, more Ukrainian soldiers are being conservative with their ammo by choosing targets more selectively.

WSJ explains how the Grad works and why Ukraine is trying to get more, despite it being outdated and imprecise.
