Prior to leaving for OCS, I was having lunch with a family friend who is a retired Marine Colonel. During the course of discussion, the subject of dropping came up and he told me of his time as an OSO about the various reasons for dropping. The concensus between us was that unless you were seriously injured, there was no reason to leave OCS any earlier than graduation day.
If you entertain any thoughts that DORing will get you out of there immediately, you are sorely incorrect. I can recall seeing the same candidates wandering around OCS for up to a week after deciding to leave their platoons. You'll just be sitting there for a few more days, probably regretting your decision to leave, despite the fact that there is nothing you can do to reverse it.
OCS will be the toughest challenge in your life as yet, but there is nothing that you cannot take for 6-10 weeks. You will come out all the better for the experience, and not just that, you will come out with the designation of an Officer of Marines. One of my friends at OCS dropped as soon as he could, and I could not for the world understand why. Don't allow this to happen to yourself. Accept that the training will get into your head at some points and make you wonder why you ever volunteered for this unique hell. Just keep your head in it, suck it up, remember why you decided to come here, and carry out the training. Good luck and get some!
