Forward support battalion

A forward support battalion was an Army of Excellence combat service support unit designed to support a Brigade. In divisions, it was part of the Division Support Command (DISCOM).

It was composed of:

• Headquarters & an A company, which provided command, control, and oversight for the battalion & quartermaster support to the brigade. However, the forward support battalions of armored and mechanized brigades would have a separate Headquarters and Headquarters Detachment (HHD) and A company.
• A B company, which provided maintenance support to the brigade both with 3rd Shop, and Maintenance Support Teams attached to the individual battalions.
• A C company, which provided level II medical support to the brigade.

With the conversion to the modular force, the FSBs are being replaced with brigade support battalions (BSBs)
