This one ended up chockful of initialisms. I tried to keep them to a minimum, but the constraints on the grid proved too overwhelming. It's a small miracle that I was finally able to fill it, even removing a few obscure entries during the cluing.
There are still a couple of obcurities left, so I went ahead and made it an easy-peasy solve. Nothing too spooky. I hope.
