I have to wonder if there's some aspect about the night vision optics that results in points of light looking like triangles.

Good call, it’s most likely bokeh.

Mick West incidentally does a number of quite good videos on UFO footage and camera phenomena.

Yep the bokeh takes the shape of the aperture blades. Typically they look like hexagons but I could see in this case of some weird military night vision it being triangles.

Here's an example of a lens with a triangle shaped aperture: https://vintagelensesforvideo.tumblr.com/post/126045282053/t...

I'm pretty sure that is the case here. I have a vague recollection of video footage from the '90s of a similar diamond-shaped UFO being explained away as a shape made by the optics of the video camera distorting a bright, not-quite-focused light [possibly Venus].
