Volunteer forces are groups of individuals who offer their time and skills to support various causes or organizations without receiving payment. These forces can be found in many areas, including community service, disaster relief, and military support. Volunteers often work alongside professionals to enhance efforts and provide additional resources. In the context of the military, volunteer forces refer to service members who enlist willingly, rather than being conscripted. Examples include the U.S. Army Reserve and National Guard, where individuals commit to serving part-time while maintaining civilian jobs. These forces play a crucial role in national defense and community support.
