I have to put in a good word for both the MIT/Harvard/Tufts Unit and the Boston University/Boston College/Northeastern Unit ("The Boston Consortium"). A lot of people have the impression that this isn't a very friendly area for the military and ROTC, but I've had no negative experiences yet, and it's really cool to be part of a small, tightly knit unit, like the MIT one. Yes, ROTC is banned from Harvard, but it's actually kind of cool to be part of a very small group of motivated individuals who represent the military to the entire academic community here. Also, if you want to go nuke, MIT is the place to be; pretty much everyone gets selected for it, and the resources for technology are amazing. The BU/BC Unit, across the river from us, is a bigger unit, and it is a very professional one. It's bigger than our unit, and BU/BC/Northeastern are great schools. Boston is amazing for college, too. Send me a PM if you want more info on either unit!
