Ukraine changed the conduct of war in its war with Russia

Truly, necessity is the mother of invention.   With dwindling budget and protracted war (and US asking for exchange with war aid)  Ukraine redefined the conduct of war.  Drones have been extensively used and even devastated wrought havoc on their navy and air force.

1  Drones destroyed many of USSR strategic  bombers,   dones destroyed multi million $ tanks, unmanned water vehicles served as launch pad vs Russian ships

2.  Drone production increased by 10 fold

3.  They used fiber optics to command drones when Russian jammed rf from controllers for as long as 12 km.  Birds use fiber optics cables to build nests.

Its not a question of who has more war materiel.  It is a question of who is more ingenious.
