I picked this up at one of the universities we were at recently in the US. Pretty tempting terms for students who are heavily in debt:
"If you've already attended college and need help paying back your Perkins, Stafford or other federally insured student loans, the U.S. Army can help. The Army Loan Repayment program can pay back up to $65,000 of your student loans. You may also qualify for the up to $20,000 enlistment bonus. Ask your Recruiter about the latest active Army, U.S. Army Reserve and ROTC incentives and college programs."
