Yoda-speak ? Okay then.
My experience:
Joined the US Navy as a Poseidon Missle Tech (requires high math scores and Secret clearance).
Recruiter calls back. No Missile Tech. I had a record for underage beer drinking. (no secret clearance for dread !).
But ! Math score meet the higher Sonar qualification (and we'll take any Sub volunteer we can lay our hands on).
Okay, I go thru boot, sub school, and several sonar schools. Then I hit the Fleet for 6 years.
I left with a "Top Secret" clearance.
At no time did I ever take a "polygraph". This "lie detector" test is mystical BS for the flock. The Scientologists have a better line of crap.
