Who should evaluate a Soldier unable to bear weight on an injured ankle?

The correct choice is the medical officer because they have the necessary training and expertise to perform a comprehensive evaluation of the injury. A medical officer is typically a qualified physician or a healthcare provider who can assess the severity of the injury, order appropriate diagnostic tests (like X-rays), diagnose the condition, and create a treatment plan based on the soldier's needs. This ensures that the soldier receives appropriate medical care tailored to their situation, including potential further interventions if necessary.

While nurses and emergency technicians are also trained in assessing injuries, their roles may not include the same level of diagnostic authority and capability as a medical officer. A fellow soldier lacks the professional training to evaluate injuries effectively and could lead to misjudgment of the situation. Therefore, the involvement of a medical officer is critical in such cases for accurate diagnosis and appropriate care.
