Question:

My 6 year contract was October 1974 thru October 1980. I was inactive reserve from October 1974 until June 1975 when I started my active duty enlistment. I ended my service as inactive reserves again until October 1980. Though I didn’t start active duty until June 1975, does the inactive reserve period of October 1974 to June 1975 qualify me for Vietnam era vet? In total, I was USN 4 years active, 2 years inactive reserve.

For VA purposes, in accordance with the Code of Federal Regulations Chapter 38 Paragraph 3.2 (f), the Vietnam Era is "The period beginning on February 28, 1961, and ending on May 7, 1975, inclusive, in the case of a veteran who served in the Republic of Vietnam during that period. The period beginning on August 5, 1964, and ending on May 7, 1975, inclusive, in all other cases."

Inactive reserve doesn't count for anything in particular in reference to benefits. Your time in the military is measured in terms of active duty for other than training. If your active duty began in June 1975 you are not a Vietnam era veteran.
