did you complete 68W school and get a 1059 stating that you are a 68W?
if no to either one, then you are not a 68W and never got awarded the MOS, so it cant be a 2nd MOS.

A. are you in a 68W slot?
B. Is this ASI only eligible for 68W, which goes back to A.
C. most schools require some amount of time left in service upon completion of the school. most of the time it is 1 year, but i know some require more 2 years+. If you look up the course in ATRRS, it should/could be listed there, otherwise your training NCO should have that information as well.
thats all i got
