Unit development is significant in maintaining operational readiness and improving the professionalism of military units. In the 2nd Field Artillery Regiment, 2nd Infantry Division, Kostrad Malang, unit development covers organizational, personnel, material, and training aspects. However, implementing unit development often faces various obstacles, such as limited personnel, material, and facilities. Therefore, this study aims to describe and analyze the implementation of unit development along with its supporting and inhibiting factors so that the unit can carry out its main tasks optimally. This study aims to describe and analyze the implementation of unit development in the 2nd Field Artillery Regiment, 2nd Infantry Division, Kostrad Malang, as well as to describe and analyze the supporting and inhibiting factors in the implementation of unit development. This study uses a qualitative method to implement unit development and its supporting and inhibiting factors. Data analysis uses the Miles and Huberman technique. The study results show that the implementation of unit development in the organizational field has been carried out through a limited assessment of personnel, material, and base facilities support, such as housing and offices, as well as training infrastructure and software from the upper command. However, the limitations of this support have resulted in the suboptimal implementation of the unit's main tasks and the implementation of liquidation in the unit. Personnel development is realized through ideological, spiritual, and fighting spirit mental care, corps tradition development, and leadership that sets an example for subordinates to maintain moral strength in upholding rules and norms. Material maintenance is carried out through routine checks at least once a month on materials and defense equipment, ranging from vehicles, electricity, weapons, entry and exit arrangements, to Alsintor, Aloptik, and Alkapsat. Although the materials are adequate, modernization is needed in line with global developments to maximize defense equipment and supporting facilities. In training, drills and rehearsals are always carried out before the actual training, with a combination of alternating training between units. The unit environment, such as offices and dormitories, is also used as a training facility.
