Left army before bct?

Hey, I left the army before I went to basic. This was the other day. The recruiters lied to me about all my job opportunities. So I told them I wanted out and they were not happy. Why were they pissed, they lied. But I know I shouldn't have signed for a job I didn't want. Anyway, I want to go back in as a tanker? I am colorblind. Can I do that? If I cannot, I was thinking usmc infantry.
