So you were interviewed by a former military recruiter? :wink: (A little joke about some of the similar complaints made by recruits.)
Assuming you did have a cause of action, in terms of trying to prove a case....
The first problem would appear to be one of fact versus opinion - is the recruiter's interpretation of your job a plausible (even if far-fetched) opinion as to what the job entails?
The second problem would appear to be one of reliance - did you rely upon the representations in taking the job, or would you have taken the job anyway?
The third problem would appear to be one of damages - if you were out of work, and had no alternative job opportunities, how were you damaged by taking this job?
And then there are issues of proof - if the recruiter denies any misrepresentation, how would you prove misrepresentation?
You can talk to a local plaintiff-side employment lawyer about the possibility of litigation. But for now, it seems that your priority should be finding a better job.
