Republic of soviet socialists were apart of the Allies during WWII so its possible the USA
one will be used instead.

yeah this is something that i would like to know aswell... If they have their own
medic, i can use my elite pot for the medic. If not, i can use my elite pot for
something else...

EDIT:

As of now, SN has NO medics. You can view the sailor tree in the game info section.

I'm wondering if they will add them though... or atleast tell us what nation will be
able to be used on the SN ships.

99% shure it will be american medics, it wouldnt make much sense to use german
medics
