For a TS-SBI, they will know who you lost your virginity to, what you REALLY think of your Aunt Agnes, and when the last time was that you had a wet dream. They _WILL_ find out whether you lied about depression on your SF-86 - it's their job to find out, because if you lie you can be blackmailed into giving up secret info to the bad guys. If you manage to survive to make it "down the road" - odds are you will be an E-5 or E-6 before you are applying for this new job - with eight or more years under your belt for service time.
You would be a PRIME candidate to blackmail for secrets, because you would have a LOT to lose if the Marines found out from an "anonymous source" that you lied to enlist. And the clearance investigators would have an easy time of it because before they start they'll have a polygraph on you - and anything that is even SLIGHTLY out of whack will have them digging harder to get to the "truth" - and they'll find out about your mental issues. Don't do it - unless you like the idea of throwing your employable life in the trash with a federal felony conviction for fraudulent enlistment.

I would be very careful about getting that TS. They will do a THOROUGH background check on you, check your references, call your family, call your friends, call former employers, pull up prior police records. The reason why I say you might want to be careful is that if you lied at MEPS, and they catch you in that lie, you can get discharged because you were recruited under false pretenses (the gov thinks they bought a lemon, and they are going to kick you to the curb).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
