Defense chiefs fail to resolve dispute on tanks for UkraineRAMSTEIN AIR BASE, Germany (AP) — Ukraine will have to wait longer to find out if it will get advanced German-made battle tanks. Germany would need to agree for the tanks to be given to Ukraine, which is not a member of NATO. The defense leaders heard an impassioned plea for more military aid from Ukrainian President Volodymyr Zelenskyy. The U.S. has resisted providing its own M1 Abrams tanks to Ukraine, citing extensive and complex maintenance and logistical challenges with the high-tech vehicles. The influx of new weapons, tanks and armored carriers comes as Ukraine faces intense combat in the country's east around the city of Bakhmut and the nearby salt mining town of Soledar.
