Hello, my name is Bob. I will be attending ROTC this fall and would like some idea of how Officer MOS selection will work upon commissioning. I am a 26 year old Journeyman plumber, had a 3.83 high school GPA, was concert master violin, and received awards such as best musician. I did not participate in Athletics in high school, but I am competitive and in good shape. I can run a 13 minute 2-mile. I will be majoring in mechanical engineering. I bring with me an excellent never quit work ethic and a hands-on approach. I already embrace Army values in my daily life and would be honored to set a positive example as an Officer and make a difference in the lives of my future fellow soldiers. I understand the Army allows Officer Candidates a dream list of 5 choices, that you are more likely receive if you are top 10% of your class. My ideal role would involve working in the field. These are the ones that interest me: !. US Armor Officer- I heard that being trained as an Armor Officer allows you to be put in command of both armored and infantry units, allowing essentially for more career flexibility. I find mechanized tactics very interesting. 2. Infantry Officer 3. Combat Engineer Officer/Sapper Officer - I have construction related experience and will have a mechanical engineering degree. I will most likely be more qualified for this occupation compared to my other choices. I have some experience with Search and Rescue, including navigation, communications, outdoor/survival and medical skills, so I have a realistic understanding of what it takes to conduct field operations. I know that being an Officer means being a generalist in many cases and not a specialist. I also understand the differences between the tactical, operational and strategic levels of command. However, I will be 31 by the time I commission and at that point I might not be the most physically qualified for some of the these active leadership roles. I am not sure if this will be taken into account when assigned an MOS. At what age/rank do Officers graduate from active field roles? Is there any chance of me becoming a Ranger Officer? And would age be more of a factor with them? I would appreciate ideas of what MOS's I should put on my wishlist and strive towards, taking my background into consideration. Realistically, what will the Army perceive me to be most qualified for? What does the Army mostly look at? Performance in ROTC, GPA and at LDAC and so on? Thank you for your assistance.
