I'm having trouble developing a character. The antagonist in my WIP.
Brief summary: There is a global threat, discovered over 50 years ago. Scientists have been working on a specific experiment at an American station on the Antarctic. The experiment (we are talking about aliens, gene therapy, DNA) is headed by an American scientist. The threat has become increasingly alarming, while the Department of Defense has been involved, they haven't been much of a presence at the facility. Until it is decided to move onto phase 2. This is where my antagonist comes in and where I am stuck. I've been to the Department of Defense website but can't find some answers.
I don't want this guy to be a total prick. He's threatened by the scientist in an intellectual way. He makes his presence known in a 'rule with an iron fist' kind of way when he is sent to the Antarctic to oversee and carryout phase 2.
In the DoD who would send my character on this assignment?
Would my character be military or civilian?
Would he have a rank or would he be called Mr. Smith?
And my first idea was to have him from the CIA, would someone from the CIA or the DoD be sent on a this type of assignment?
I have so many questions because I'm a little apprehensive to dig deep into the CIA and the DoD on the internet.
