This study aims to determine the application of criminal law to acts of violence committed by the TNI which affect psychology and constraints on law enforcement in protecting victims of violence. This study uses a normative method with a statutory and conceptual approach. The result of this study is that legal protection for victims of domestic violence according to Law Number 23 of 2004 concerning the Elimination of Domestic Violence is urgently needed because all forms of violence, especially domestic violence, are violations of human rights and crimes against human dignity as well as other forms of discrimination. Victims of physical-psychological, sexual violence and neglect experience suffering and loss, so it is necessary to protect the rights of victims to obtain justice. Justice handed down to TNI members who commit crimes of domestic violence (KDRT) can be subject to disciplinary sanctions by their superiors, in this case military discipline laws can be imposed by superiors who have the right to punish (Ankum) then if the criminal element is proven then it will be resolved through a military court.
