I have searched "Leatherneck.com" for this answer and while i have found similar threads, I havn't found anything that specifically answers my question. So..
If you are guarenteed Pfc. in your contract before you ship, is it possible to achieve LCpl (should one prove to be a meritorious recruit) where others not guarenteed Pfc. would earn Pfc. in boot camp? I hope that makes sense. Thanks for any replies.
