On the Instruction of Candidates, https://aloweb.usafa.edu/candidatekit/CK/Forms/OnlineInstructiontoCand2018.pdf 1. Page 4, it says " Letter of recommendation are not required but was strongly encouraged you to submit in addition to the school official's evaluation of candidate ( USAFA from 145). 2. Page 4 also mentioned " A resume is required" under Candidate Activities Record ( USAFA Form 147). But none of them advised how to submit the letter of recommendation and resume. Should they be mailed ? To where? What is the requirement , like the amount of the characters? Thank you!
