Wouldn't rely on these too much, we've seen them in (in)action in Venezuela

We have also seen them in action in Russia/Ukraine though.

Used against the US? When was that?

True, Russia's air defenses are trash.

Is there any Russia war equipment that they excel at?

Seems like since the Russo Ukrainian war we have learned that their tanks suck, their aircraft sucks, their boats are being sunk by defenders without a navy, even their personnel equipment sucks.

Against NATO planes gifted to Ukraine. Neither side can really use traditional air power, because both have S-300 launchers.

Their cyberwar capabilities are pretty good

Ukraine is running a leftover buffet of export variant jets against a domestic S-300, so the results might not be comparable when roles are reversed, which was the case in Venezuela. Surely other factors were at play as well, but the US probably has other means at their disposal for dealing with air defense. But let's see, I'm only armchair generaling and hope none of this becomes relevant
