surface to air, why do i doubt that...
the pics/video show at least two smoke trails before it’s launch
so they fired three at unknown aircraft, two misses and one return to sender all while on video, anticipating launch, to an unexpected aircraft attack, is that it?
using them as surface to surface maybe?
Surface to surface is how they’re being used in a lot of places by the Russians.
Your doubts are well-founded
S-300’s are launched in pairs not 3’s
Russia is regularly destroying Ukrainian S-300 systems
being provided by 3d countries and has no shortage
of accurate missiles used to take out weapons depot, fuel,
troop concentrations and recently, high level military planners
