A certificate on the circumstances of the injury is a document that is the basis for compensation for the damage suffered. To obtain this document, a serviceman must submit a report to the head of the unit or to the medical institution that provided him with medical care. You should add to the report your explanation of the circumstances of the injury in an arbitrary form. If any of your co-workers saw you get injured, they should also write such an explanation.
The commander of the military unit issues an order to conduct an official investigation and draw up an investigation report, and the authorized officer collects the statements of the victims and witnesses, describes the events and draws up the corresponding investigation report. The commander of the military unit signs the certificate on the circumstances of the injury and sends it to the health care facility where the injured person is staying.
