Um, I hate to be the bearer of bad news, but if you were Infantry in the Corps and you don't get WOFT, you will be Infantry in the Army.
When I crossed over from the Corps to the Army in '99, they allowed me to pick a new job because my MOS in the Corps (0842) wasn't critical in the Army.
However, things have changed. We now have a war going on so if you were ANY combat arms in the Corps, you can forget about re-classing. You will be an 11B, period, no other options.
I just ended 4 years of Recruiting (God it feels good to say that!) When I started, we could let prior service be picky, but in the last 2 years, unless your prior MOS is locked up in the Army, you will not re-class.
You may want to clarify a few things with your Recruiter. Sounds like you aren't getting good dope.
