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.

On Tuesday, Ukraine also reported enduring an immense Russian air assault overnight that involved nearly 200 drones, as both sides intensified air attacks.

Russia launched another attack on Ukraine's energy infrastructure on Thursday, leaving over a million households without power and forcing emergency power to be implemented nationwide.
