I agree with that aeseven... Lots of quality effort on that figure. I see the Navy SEAL roots there with some of the parts, but there's unique elements that make sense for aquatic Clones like the head lamp, the bulk... Short of a little propulsion accessory (a Sea-Do type thing, SW style) it's pretty unique. The pistol's even cool as it looks special for that trooper.
And of course our current one from TRIER we have for the giveaway here at JediDefender.com is equally well thought-out I believe. Some quality aquatic Clones out there for something not even seen in the films!
