Yes, it's trench war. No, drones nowadays pay huge role in combat - fpv drones take out majority of fighting vehicles, terrorize and kill humans in trenches by dropping grenades, by striking inside of covers, other drones put mines, etc. It became a big problem for both sides so that most of supply and forces rotation is done at night. But there are also fpv drones with night vision. Drones became a pillar equal to artillery due to their cost and effectivness - single fpv costs $800-$1500, one artillery shot costs more. Plus drones have higher success rate.
