CHARLESTON — About 2,000 Citadel cadets are participating in what the college says is the largest community service event in the history of the Charleston military school.

Tuesday’s event is called Heroism Day.

Nearly 800 cadets are visiting visit local schools to discuss heroism with students while hundreds of others are working at food banks, animal shelters and community centers. Hundreds more run from campus across the Ravenel Bridge to Patriots Point in Mount Pleasant in honor of veterans.
