The elite 47th Mechanized Brigade, the main user of Ukraine’s American-made armored vehicles, was in bloody combat for 15 months before it finally rotated off the front line this fall—but even this belated break came to an abrupt end when Ukraine’s invasion of Kursk Oblast in western Russia drew the brigade back into action.

The Russian military launched a major missile and drone attack on Ukraine early Thursday, leaving hundreds of thousands of homes and businesses without electrical power.

Russia launched more than a hundred drones at Ukraine overnight and early Friday, killing one person and wounding eight others, officials said.
