Homeless veterans are individuals who have served in the military and are currently without stable housing. Many face challenges such as mental health issues, substance abuse, and difficulty reintegrating into civilian life. These factors can contribute to their inability to secure and maintain housing. Efforts to support homeless veterans include programs from organizations like the U.S. Department of Veterans Affairs and various non-profits. These initiatives aim to provide resources such as temporary housing, job training, and mental health services to help veterans regain stability and improve their quality of life.
