The chapter presents crucial aspects of the theoretical background of social campaigns as a form of informal learning about service-connected disabilities. Service-connected disabilities affect all aspects of veterans life, such as employment, education, family, and social life. Such a situation needs deep analyses of creating a comprehensive supportive system for veterans with disabilities, which includes compensation, career counseling, job search support, therapy, and group meetings. Activities related to the support provided to veterans with disabilities are also concerned with social actions. Social actions are crucial elements of informal learning, as their creators use engaging strategies to present socially valuable ideas or values. Social campaigns as collective actions aimed at enhancing change in critical social areas contribute to raising awareness, changing attitudes, and organizing support systems for people from groups at risk of social exclusion, including veterans with disabilities. Social campaigns facilitate ongoing engagement and gather communities around similar goals, which are spreading knowledge about crucial social issues. Campaigns about service-connected disabilities contribute to social inclusion in local, national, and global contexts.
