I sometimes think these small wars are going so large nations can test their equipment to see what works and what doesn’t.
I think that has always been a goal of groups that develop weapons, going back centuries.
Real interesting to see Ukrainians attaching claymore mines and bombs to drones, and using them with great effect against motorized armored vehicles and ground troops. One video I saw, had Russian soldiers running around an armored vehicle while trying to flee from a drone chasing them, round and round, but killed when the claymore mine detonated during the chase. Imagine how effective they will be with AI rather than remote human operators.
