"For now, that means assembling prefabricated materials into underground shelters
using a Soviet-era design. They have already shipped 123 of the 2-meter (6 1/2-foot) -wide, 6-meter (20-foot) -long structures structures to areas that include eastern Ukraine’s Zaporizhzhia and Donetsk provinces. Each shelter requires nearly 2 tons of steel. The bunkers are built to withstand projectiles with calibers of up to 152 millimeters, can accommodate up to six soldiers and need to be buried 1.5 meters (about 5 feet) underground." (Emphasis added.)
Unfortunately, the article doesn't contain any useful images of said pre-fab bunkers. I'd love to see a schematic.
In the T2kU, I'd reckon the Soviets would have seeded scores, if not hundreds, of these bunkers across Poland during NATO's initial push east.
