Well, it's in the thousands. Armenia literally announced total mobilization of their entire country, asking civilians to grab whatever they can and charge east to fight Azerbaijan. This definitely ain't no small skirmish anymore.

Armenia is definitely part of the conflict, the armed forces of Armenian NK are basically an extension of their own. Hell, officials who served in the "Republic of Artsakh" government went on to serve in the Armenian one and RoA has direct representation in Armenian government. They just don't officially recognize it because it would mean a whole heap of political headaches for them that would weaken their political position more than it already has been (though that might be changing now with Pashinyan pulling out all the stops). Azerbaijan is actually the one handicapped here because Armenia can directly attack them, claim it's actually Nagorno-Karabakh's forces and Azerbaijan can't attack Armenia in response, only keep pushing into NK.

Russia sells weapons to Azerbaijan, it gives them to Armenia for free (there was a hilarious moment about this recently where Pashinyan complained to Putin that the missiles Russia gave them are busted - Putin replied that they have ones that work but they cost money). This is why Armenia is in such deep shit now, this is the first conflict with Azerbaijan where they haven't had massive Russian backing because their government has been shitting on Russia and Putin for too long. France seems to have stepped in to send them some supplies though and Russia still sends them some stuff through Iran, even though it's less now. And apparently they have some Kurdish militants fighting for them now although that is uncertain much like the Syrian mercenaries for Azerbaijan story.
