The Armed Forces of Ukraine widely use various trailers alongside trucks. Many feature van bodies that house personnel, laboratories, repair workshops, field kitchens, electronic systems, or medical stations. These trailers typically include electrical lighting, power supply, and heating systems. The 2-PN-2M trailer with its universal closed KP4 van body serves as a common example. Following established tradition, such trailers are commonly known as KUNG — an acronym for “unified zero (normal) dimension body”.
