One Station Unit Training, sometimes referred to as One Site Unit Training, is a term used by the United States Army to refer to a training program in which recruits remain with the same unit for both Basic Combat Training (BCT) and Advanced Individual Training (AIT). Immediately following Basic Training, the unit seamlessly transforms from a BCT unit into an AIT unit. There is no relocation and the same Drill Sergeants who conducted the Basic Training will continue to instruct all of the participating recruits in their Advanced Individual Training. This streamlines the training schedule and helps to produce more camaraderie between trainees. There are a variety of Military Occupational Specialties (MOS) and training stations that have OSUT training.
