Combat roles refer to specific positions or functions within a military unit that are focused on engaging in direct combat with enemy forces. These roles can include infantry soldiers, who are trained to fight on the ground, and special forces, who carry out specialized missions. Each role has unique responsibilities and requires different skills and training. In addition to infantry and special forces, other combat roles may involve support positions, such as combat medics who provide medical assistance on the battlefield, or artillery crews that operate heavy weaponry. Together, these roles work to achieve military objectives and ensure the effectiveness of operations.
