If he got a 43 on his ASVAB, he is more than qualified to serve. And hanging these E-4 corporals out to dry for signing him up is pretty lousy.
What a load of crap. Ray Charles could get a 43 on the ASVAB too, wouldn't make him qualified to serve in the military. The ASVAB test is not the sole indicator of a person's ability to serve in the armed forces, and you know that. If it was, the recruiters would all be hanging around down at the Goodwill training center downtown, trying to recruit all the handicapped people, because I'm sure it would be pretty easy to talk them into signing the papers.
If we take your lame brain hypothesis that passing the exam automatically means that a person is qualified for the job, then it must be OK for Charles Manson to open a daycare facility if he could pass the state licensing exam.
I went to basic with a guy who had obviously passed the ASVAB exam, since he was in basic training. He had signed up for a very technical job which would require him to spend a lot of time studying techincal manuals. The problem with that was a small technicality called ILLITERACY. Yep, he couldn't read, yet he was signed up for a job as a laser repair technician, which would require a high level of reading ability to comprehend the technical manuals.
How did he pass the ASVAB if he couldn't read? His recruiter told him to answer "C" to every question. He Charlied the entire test, and got enough right answers to qualify. He was discharged and sent home after his 2nd week in AIT. They didn't discover he couldn't read in basic, or he probably would have been sent home from there.
