Barron, while I understand your plight to want to be a Marine at all cost, please don't take the advice of a person whose sole mission on LN.com is to be the board contrarian. He does not have your best interest at heart.
Though most who enlist fraudulently do not get caught, many do. Do you want to take that chance?
Check out these two links:
This one will explain what actually can happen to you if you are caught after fraudulently enlisting -

This one has examples of people who got caught and what happened to them -

Again, don't just take the word of somebody who has nothing to lose if you get caught. Do a little research on the web. There are many examples out there if you google "consequences for fraudulent enlistment".
