LION 8 is not a unit per say, it is a location of a WWII Advanced base to which he was assigned.
As member 29navy posted above, LION is the code name for a Naval Advanced Section Base (NavAdvBase) Here's the excellent source he posted http://www.ibiblio.o...nceBases-6.html
In May of 1945, LION 8 was Nav Adv Base Unit #8 & Nav Section Base, Zamboango (different spelling = Zamboanga) Philippine Islands.
If you have access to a Fold3 account, some of the records of the base are listed there
