No. You were not a student. You were a soldier, on duty, doing the job you are being paid to do. Even West Point cadets are not considered students, for tax purposes.
So, a person who attended technical school while a member of the military is not eligible for education credits on a tax return, nor is he considerd as being a student for purposes of being a "Qualifying Child" dependent.
However, basic training and advanced individual training, are considered temporary absences from your parents home, for the dependent test. But, I don't think a 13 month technical course would meet that criteria. So, for example (and it's a common example), you graduate from high school in May and leave home to join the army. Your basic and AIT training take 3 months. You still qualify as your parent's dependent because you were a full time student (HS) for parts of 5 months and were still considered as living with them for more than half the year (military training was only a temporary absence).
