How many organic companies are in a Combat Sustainment Support Battalion (CSSB)?

In a Combat Sustainment Support Battalion (CSSB), there is indeed one organic company, which is the Headquarters Company. This company is vital as it provides command and control, administration, operations, and logistics support for the battalion. It acts as the backbone of the CSSB, enabling effective coordination and communication across various units.

The other options refer to types of support companies that may exist within a sustainment brigade or different configurations of logistical support, but they do not represent the essential structure of a CSSB itself. The presence of multiple companies, such as operational support or medical support, may depend on particular missions and force structure but does not define the organic composition of a CSSB, which distinctly includes a single Headquarters Company. Understanding this structural organization is key in grasping the role and capabilities of a CSSB within large-scale combat operations.
