It would seem to me that you have hit one of those wonderful walls in the ethics of the inabsolute. It would seem that you need to conclude what degree to which you are comfortable being involved in a system of violence. While not ALL of what the DoD research does is violent, it is the formally sanctioned instituion by which we as a nation effect violence upon others. Now on another, but still related note, to some extent all Americans are involved in a vilent system of oppression, as we violently oppress others with our consumption and political strucure in either manifest or latent forms.

So in working for the DoD, in your perception, would you be participating in such oppression too greatly? would your involvement in the organization, regardless of involvement amount to adding to the violence? These are questions we cannot answer for you.

However, if you were asking me, I would never trust anything Rummsfeld ever ran. Violence, intolerance, homophobia, oppression, and evil aside. Hes creepy.
