A NEVER-ENDING SUPPLY OF DRONES HAS FROZEN THE FRONT LINES IN UKRAINE

Summary from the TLDR newsletter

Drones are dominating the battlefield in the fight for Ukraine. Both sides have hundreds of them constantly in the air across the 750-mile front line. Drones can lay mines, deliver ammunition and medication, and even evacuate wounded or dead soldiers. They are being used to spot movement along the front line and dispatched to strike enemy troops and vehicles. Drones are so cheap to make that both sides can expend them on any target, including individual soldiers. Due to their size and speed, they are difficult to shoot down, so the main defense against them has been electronic jamming systems - but these can be overcome with fiber-optic drones.
