Even the switchblade doesn't have a massive impact in ukriane .loitering munitions are almost not that effective there
Switchblade 500gms warhead was always a stupid idea to begin with, most of other loitering munitions start with 1.5kg warhead atleast.
Effectiveness of loitering munitions lie in their ability to loiter and wait for the perfect moment to attack a preset designated types of targets to get out the most of value.
Here is a excellent use of Russian Kyb munition perfectly hitting and effectively taking out a whole infantry section.
I am quite sure that if availability of mini uavs for surveillance and light loiter munitions like warmates or solar lm0 goes upto depths of platoon level or atleast company level, it would greatly increase the chance of taking out high priority enemy tactical targets like snipers, Mg teams, atgm teams, spotters, mortars team etc.
