I cannot believe I am even reading this from someone who dares call himself a Marine Officer.
If you have serious family issues (i.e. you have to care for your younger siblings because your parents got cancer/died in a fiery car crash) or there is something seriously messed up about your health (you have asthma) or you are in violation of the don't ask don't tell policy, there might be grounds to drop your commission.
99.99% of the contributors on this board's gut reaction (mine included) is "Who the F is this sh--bag boot LT who wants to leave the marine corps because they have to spend some extra time in Mike company?" Are you serious?
PLEASE feel free to enlighten the rest of us with the details of your predicament if you want serious advice about this, because right now you're just begging to get flamed to death.
I may be stretching, but judging on your recent posts involving complaining about the details of your committment time for aviation, and 'so is it true that xxx can get you kicked out of the corps??' questions, your motives are HIGHLY suspicious seeing that they're all posted within hours of each other.
These are the kinds of questions you should expect from pre-OCS people, NOT officers who have already accepted their commissions. You need to either sit down and have a serious evaluation about your future life as a Marine, or go get immediate counseling from your Chaplain/OIC/XO. In a few months you could be leading Marines to their deaths, or in a few years behind the stick of a helo with a platoon of grunts in the back and in your hands, and here you are whining about not liking Mike Company?
On second thought, maybe you SHOULD find yourself a way out of my Marine Corps, and FAST.
