What is a low density MOS?

A low density Military Occupational Specialty (MOS) refers specifically to a specialty that is essential but is only applicable to a very small number of soldiers within the Army. This can occur because the skills required for this MOS are unique or specialized, and not as many soldiers are trained in these areas compared to more common MOSs. In many cases, these low density MOSs are crucial for certain missions or roles, but due to the specific training and skill set required, the overall number of personnel assigned to these specialties is low.

For example, a low density MOS might involve highly technical or specialized duties that require advanced training not everyone in the Army will receive, such as certain positions in cyber operations or specific intelligence roles. This relevance of low density MOSs emphasizes the need to maintain a pool of qualified soldiers for critical tasks even though they may constitute a smaller percentage of the overall force structure.
