What Are Reserve Military Forces?
Reserve military personnel are trained individuals who serve part-time while maintaining civilian jobs. They undergo periodic training and can be mobilized for:
✅ War and armed conflicts
✅ Natural disasters & emergency response
✅ Peacekeeping & international missions
✅ Support roles (medical, engineering, logistics)
Unlike active-duty soldiers, reservists are not full-time military members but are essential for rapid military expansion during crises.
