Which is NOT a standardized design of the Army Brigade Combat Teams?

The Army Brigade Combat Teams (BCTs) are structured around a standardized design, which includes Infantry, Armored, and Stryker BCTs. Each of these types is specifically organized to fulfill distinct operational roles on the battlefield.

While the Infantry, Armored, and Stryker BCTs each have defined configurations and roles within the Army structure, the term "Artillery" does not refer to a type of Brigade Combat Team. Instead, artillery units are typically found within these brigade types as supporting assets rather than as standalone BCTs. The artillery elements are integrated into the various BCT formats rather than existing as an independent standardized design. Therefore, when assessing the BCT structures and their standardized designs, "Artillery" does not fit within that framework, and this distinction is key to understanding the question.
