Who is Danny Huston?

It may be that he is just a leader of the German army and Diana, inexperienced as she is, goes for the overkill. However, I do believe that they know each other. While Diana knows him as her target, the way he looks at her suggests that he knows why she is there.

And just as Diana reaches for her sword, hiding her arm, Danny Houston does the same thing. One of his arms is hidden. We don't know at this point whether he also has a concealed weapon or not. But I can bet that he is aware of the existence of the Amazonians, as the trailer will later reveal (I believe).

Thus, this leads me to believe that he is Ares. And the God of War has all the reasons to be behind the first major conflagration in humankind's history. Don't you agree?

And he must know about Themyscira. Because later on in the trailer we see the awesome fight between the Amazonians and the human soldiers. Who told them about the island? Furthermore, I do believe that these aren't mere soldiers, and that they have been imbued with special powers by Ares. Otherwise, I don't see the reason why the Amazonians will go for the overkill "“ why would Robin Wright use multiple arrows in order to kill a simple mortal?

There is also that woman wearing the creepy prosthetic mask "“ who is that? I can bet that she is also an Amazonian, one that has switched sides.
