Combined arms drone style

Russian infantry seek cover in a trench system, harried by drone-dropped munitions. Once immobile in the trench system, FPV drones swoop in like birds of prey and pick them off. In conflicts past, trenches offered protection from direct fire weapons and all but direct hits from indirect fire munitions. In twenty-first century warfare, FPV drones have transformed trenches into deathtraps for the soldiers who dug them.
