Is there a difference between officers from SA or ROTC? I understand they both start as 2nd LT, but as far as choice of branch, promotions, other prospect.. are they same?
Once you’re on active duty, there is no difference. The army doesn’t care about where you came from, just how well you’re performing and your potential for continued contributions.
For everything leading up to it, there’s definitely differences between the programs and both have their pros and cons. Coming from a SA, you have much more control over your destiny for branching because of how branching is structured as best needs of the Army combined with competition only against your classmates. Additionally, West Point has to commission a certain percentage of combat arms officers every year. There’s a lot less left to chance if you do well at a SA about knowing what branch you’re going to come out as.
Second, you’re guaranteed active duty coming out of a SA. ROTC will be the first commissioning source always to be cut for active duty slots, and it can be competitive to get active duty depending on the political climate of accessions at the time.
For everything else, it’s user preference. West Point has a ton of money to send cadets to schools and provide summer training most ROTC programs won’t have a shot at, but you’re living at a military academy for four years. Academically, West Point stands it’s own for broadening experiences that bright side, will be fully funded by the school. ROTC has some neat programs for cultural immersion as well. For day to day life, there’s a lot to be said for going to a normal school/doing ROTC and figuring out how to be an adult in the real world many SA graduates don’t seem to figure out until after graduation (flight school was an interesting time for many of my classmates). Some of my peers would not have done well at all in a SA environment but they’re good officers now and vice versa, for many of my classmates, the structure provided by a SA was what we needed to develop into the officers we are today.
At the end of the day, there will be great officers that excel coming from ROTC and OCS as well as USMA. There will also be bad ones. Your soldiers don’t care. They just care about what you’re doing for them now.
