More than 100 active duty Camp Pendleton Marines were putting up tents and other facilities in preparation for the 23rd annual "Operation Stand Down."
The nationwide program was put in to action to help get homeless veterans off the streets.
The three-day event will kick off Friday at 6 a.m. for vets living in San Diego County. They will be given food and warm clothing among other resources.
"It's a difficult problem because here men and women sacrifice for us," said Tom Mitchell with the Veterans Village of San Diego. "And now it's time to give back to them. Some of them have come back with very difficult problems and very difficult issues. We are trying to give them a step forward. It's really a hand up not a hand out."
Last year, more than 900 homeless vets showed up for help.
