Through their focused efforts on demolitions and mine disposal, the UDTs refined and developed their commando tactics during the Korean War. The UDTs also accompanied South Korean commandos on raids in the North to demolish train tunnels. This was frowned upon by higher-ranking officials because they believed it was a non-traditional use of Naval forces. Due to the nature of the war, the UDTs maintained a low operational profile. Some of the missions included transporting spies into North Korea and the destruction of North Korean fishing nets used to supply the North Korean Army.
