 Officer Candidate School. It is where college graduates and prior enlisted Marines prove that they have what it takes to be a Marine Corps officer. Right now our main mission is to train, screen and evaluate potential Marine officers and make sure that they have the leadership ability that we would want of a Marine officer. Being a leader is one thing but truly being responsible and understanding and caring for their Marines is probably the most important thing that they're about to undertake. These candidates are tested physically and mentally. A lot of PT, a lot of fast eating the chow, a lot of knowledge, just learning everything to become the essentials, the basics of a Marine officer. This year marks the 75th anniversary of Officer Candidate School at Brown Field. That first class was the first example of great Americans who went on to do great things. And that legacy has gone on to today. It's the screening, it's the evaluating of these young men and women that is so important. And we've done it over the past 75 years which has made us the legendary fighting force, probably the best in the world that we are. The next step for these newly commissioned officers is to finish the basic school and learn the skills they need to lead the future of the Marine Corps.
