Hard to tell with all the ghost targets you get with ADS-B Exchange, but it looks like they are going to have Spartan 620 pretty soon. I also spotted Guard 820 near Mather, but I have no other info. I’d rather think if its CalGuard, they’d maybe want to bring a CH47, or the like.
This definitely looks like Spartan 620 and CalFire 606 are getting ready to do something. Again, no info on whether these are evac or buckets.
