That is correct....I enlisted for 4+2 (got a guarunteed promo out if bootcamp and and skipped from E2 past E3 straight to E4 afyer finishing my 1st sonar school.... 5 months from E1 to E4....)
I was on hook for another 2 yrs inactive reserves (got the pink ID card atill) after that.
At the time (enlistment ended 8-4-92) the rules basically said tjey had to reinstate the draft beforr they called me back....barring a critical need for my specific job.
Presto PO here, too. Spent a year in electronics and sonar school in San Diego in ‘66 - ‘67. SQS-26 BX. Played a lot of pool in the barracks. :)
