The Bob Woodruff Foundation and Stand Up for Heroes have raised more than $28 million to date. These funds reach more than 2 million service members, support personnel, veterans and their families to help them when they come home from the battlefield, making sure that they have access to the support and resources they need, for as long as they need it, according to organizers.
