Minifig.Cat's BrickLink store just posted 19 new items which I believe originate through Si-Dan Toys. The bulk of the items are listed as 'Navy Seal'; however, there are some spartan warrior accessories too.
If you enjoy Tiny Tactical and BrickArms, you may want to check them out. The items are currently on display at Minifig.Cat's Flickr stream and their BrickLink store.
