A special troops battalion (STB) is an organic unit of a modular brigade, division (or equivalent), corps or higher echelon United States Army organization.
Under the brigade organization introduced by Army Chief of Staff GEN Raymond Odierno Infantry and Heavy Brigade Combat Teams special troops battalions will get another combat engineer company and be reflagged as an engineer battalion.
The formerly separate companies in a Stryker brigade are to be combined and flagged as an engineer battalion.
[1] In the sustainment brigade, the battalion is composed of an HHC and a signal network support company.
When deployed, the battalion will usually have a financial management (FM) company, postal, and a human resources (HR) company attached to it for command and control (C2), administrative and logistics support.
