That picture of General Hawk is wrong I think - That's a navy uniform, so its probably from some other movie.
Generals have stars - Admirals have stripes - Although in this picture he has stars on his shoulders, the dress uniform is blue/black which tells me Navy and not Army (Army is green/beige/brown me thinks)
(I think it was on some site I saw as well, and I immediately went

)
And just to clear things up - The picture of Quaid is not official until the studios says so, so far there are only 3 official pictures out, 2 of Snake Eyes and one of Scarlett. (I'm betting they will throw a lot more promotional shots out before anything else). The sneak peaks underneath my post here for example (of duke and the baroness) are not official, but from the movie.
The name tag might be photo edited - any Quaid fans out there that knows if he has played a Navy Admiral in some other movie?
