Here's what RPI states on their 2015-2016 Catalog regarding the Room and Board Scholarship:
"
ROTC Room & Board Scholarship The ROTC Room & Board Scholarship is awarded to all ROTC scholarship recipients attending on a full-time basis. The ROTC Room and Board Scholarship is equal to the average room and board allowance provided to non-ROTC students residing on-campus as determined by the Office of Financial Aid. If an ROTC student is receiving a Rensselaer merit based award, the student will receive the merit award s/he would otherwise receive or the ROTC Room and Board Scholarship, whichever is greater except as follows:
The sum of all other grants and scholarships (including ROTC Scholarships) cannot exceed the cost of attendance determined by the Office of Financial Aid. In such cases the ROTC Room and Board Scholarship and/or other Rensselaer grants and scholarships are adjusted."
