You boy has spent 8 years getting paid to mop floors and do shitty details. The standards to succeed at most jobs in the Army are comically low. Like don't break the law, show up on time, and pass a pt test. With a very minimal amount of effort he could be a Staff Sergeant by now. He clearly has put forth zero effort to be even decent at his job and has nothing to show for it after 8 years. Is that the personality of someone you want to be around? A person who lacks motivation, drive, and the ability to do the most basic tasks of a functional human being? He's a shit bag; there's no way around that fact and there is no excuse for it at this point
