I'm going in circles here, but the question remains, why was he separated under 1162 and 1163? Is this common, or not?
Sorry Js. Its confusing...LOL
Apparently the guiding references for his original discharge were 10 USC 1162 and 10 USC 1163, as well as BUPERSMAN 383 9300. ( Naval Bureau of Personnel Manual)
All of these deal with involuntary seperation, which is a different category than Honorable Discharge.
Hope that helps.
