Possible SEAL patches?

Hi all,

I was wondering if anyone recognizes any of the patches in these pics?
The alpha patch reminds me of ST8, 3 troop, A platoon.

Thanks for your help!

Fred

anyone has an ID?

btt...

A patch like the top one just sold on Ebay yesterday for 35 USD. Not a lot of money if it would be a SEAL piece. Has any one ever seen this design before?

Found this on Ebay (identified as NSWDG Grey Squadron). Still not confident about this ID, but I'll keep looking.
