2-69. There are three types of BCTs: armored, infantry, and Stryker. BCTs normally operate as part of a division. However, they can operate outside of a division headquarters structure directly for a corps or higher echelon commander. In this case, that higher headquarters assigns the BCT its mission, AO, and supporting elements. That higher echelon headquarters orchestrates the BCT’s actions with other elements of the larger force. Figure 2-5 shows the organization of an armored BCT.
