While it is much, much cooler to think that some Deep Black milsats
were duking it out with laser beams weapons and particle cannons, I
wonder if you in fact saw some "flares" off the solar panels off one of
the 72 Iridium satellites in Earth orbit?

Note this quote:

Soon after the initial launch it came to the notice of amateur satellite observers that one got some very bright reflections from these satellites (magnitude -8), in certain parts of the sky. Paul Maley of Houston Texas, published the first photo of three of them flashing together when these three were still close together after launch. He also obtained the first video of a "flash" and ascertained details about the geometry by personal enquiries.
