I was going to lie about it and my buddy who was already in told me my bad knee would surface before the first week of basic training was over... I hadnt considered that.
I could see that...but Asthma - especially for those who had not had issues in a year or more...I don't see a need to bar them from enlistment. But that's my opinion. A bad knee - especially an ACL repair or reconstruction would definitely surface or probably get caught
