I am considering an enlistment with the Army through a waiver (prior service with the Navy) and I am interested in the Patriot Fire Shape Enhanced Operator MOS. I do not quite understand the difference between the 4 categories and the Army website does not specify the differences.
Can anyone who has experience with this MOS tell me more about the specifics, what to expect in this MOS and is it a good MOS for promotion prospects or warrant officer transition in the future? Impartial feedback about pros and cons is appreciated.

Pretty sweet gift currently attached with this MOS at nearly 30,000 plus an additional 16,000 to abandon to BCT in less than 30 days after signing your contract. Not a bad bargain at all!
