Many veterans returning from Iraq and Afghanistan have embarked on a new mission, but this transition from battlefield to university classroom isn't always easy.
Colleges and universities are offering an array of services, from tutoring to setting up veterans-only lounges, to help them succeed.
Some of the challenges the veterans face are medical, some academic.
Veterans often have to sharpen their math, reading and study skills after being away from school for so long.
They face cultural hurdles too.
Many other freshmen are testing their independence after moving away from home.
But many veterans are returning to school while supporting a family, working evenings and weekends.
They also must navigate the Department of Veterans Affairs bureaucracy to ensure that their tuition and housing expenses are paid on time.
