The United States has launched an expanded combat training program for Ukrainian soldiers. The top U.S. general, Mark Milley, the chair of the Joint Chiefs of Staff, toured a U.S. military base in Germany on Monday as Pentagon advisers began training about 500 Ukrainian troops in the use of advanced weapons systems including artillery, tanks and missiles. General Milley’s trip came just days after British Prime Minister Rishi Sunak said the U.K. would ship advanced tanks and hundreds of armored vehicles and howitzers to Ukraine, becoming the first Western nation to supply such offensive weaponry. On Sunday, NATO Secretary General Jens Stoltenberg said he expects other allies will soon follow suit.
