A Ukrainian engineer is trying a novel method of mine-clearance: adapting a farm excavator. Video shows whirling chains strike the ground as the digger moves forward, blasting hidden mines. The design takes inspiration from the WWII-era Sherman Tank, some of which were also kitted out with spinning chains to clear mines, Reuters reported. A commander speaking to The Post also said that Western-supplied mine-clearing equipment has proved a disappointingly easy target for Russian artillery to strike. On Monday, the US announced a new $200 million aid package to Ukraine, which includes de-mining equipment.
