Looking for an anime

I have been searching for this anime for years. I can’t remember the name, but I can remember the opening scene and a rough image of the cover art on the VHS.

The opening scene is the slaughter of a bunch of military men by a woman with green hair and a sword. She is being observed by a reporter who is taking pictures of the chaos. I remember distinctly one soldier gets stabbed through the back of his throat. I think the reporter was wearing a blue jacket and had brown hair.

The cover art is of the woman. She is scantily dressed (if at all) and, if my memory serves me correctly, there are serpents on the cover.

I was a kid when I saw this, so this is definitely an anime from the 80s-90s. Rented it at Blockbuster.

Any help would be appreciated!
