Alex, thanks for the very applicable reminder. I've been living with this as a constant reminder weekly, if not daily, due to my achilles injury and my slow progress back to good condition. I've had enlisted personnel and officers at my NRD flat out tell me that if I don't meet the minimum requirements to be an officer (in my case, the lack of running for over a year had resulted in me gaining weight and being out of standards) that I likely would meet the enlisted standards and will fulfill my obligation as a non-designated stryker for two years, etc. Many people do not consider the implications of the contract that they agreed to, and think that because a direct ascension officer candidate can DOR and go home that they can - that's not the case.
My two cents: if you're in a situation where you're considering DOR, think about the reasons why you enlisted in the first place and how those reasons are much greater than the reasons for wanting to quit. OCS is a very brief phase of our military lives, and though it may seem tough and nearly impossible to complete thousands of others have made it through to the end, and you can too. OCS is mainly an orchestrated mind-game with education and physical components, so let the political stuff and the headgames blow by, don't take anything personal, and get on with your career like you originally planned. After your commitment is up, you can do with your life as you please (the Navy owns you until then) but you'll thank yourself in the end that you stuck it out and made it through. Having to drop out and serve under some of the very same people you worked with side by side at OCS is bad enough, but even worse you definitely do not want to be dishonorably discharged.
Life is short, military careers are even shorter; take what is given to you and make the absolute best out of it and I guarantee you'll come through everything all right.
