You should have a copy of EVERYTHING the army has. If you read the contract...the contract itself "may" not be that important...for "getting out of the army"; the contract is usually important ONLY when an agreed upon "training" or "school" has been agreed to. When a breach of contract has occurred for that particular training/school, then the contract would be needed to clarify the error. Follow (trace) the very first document that was made from the contract, THAT might list the important items of agreement that you wish to contest.
