The Engineer organizations organic to the BCT are optimized to perform combat engineering tasks (primarily mobility with limited capabilities in countermobility and survivability), with geospatial engineering teams providing organic capability.

9 Additional engineering support (combat and general) comes from Engineer organizations that are task-organized to the BCT or that provide support from echelons above brigade (EAB) organizations. This manual is aligned with current BCT doctrine (see FM 3-96) and describes Engineer support for the armored brigade combat team (ABCT), infantry brigade combat team (IBCT), and Stryker brigade combat team (SBCT). Although the security force assistance BCT and its respective Engineer battalions are not addressed in detail, the basic principles of this manual also apply to those organizations. The principal audience for ATP consists of commanders, officers, noncommissioned officers (NCOs) , and staff at the BCT level and Below as well as EAB units that support BCTs.

10 ATP is a primary manual for instructional purposes within the United States army Engineer School and assists other army branch schools in teaching the integration of Engineer capabilities into army operations. Commanders, staffs, and subordinates ensure that their decisions and actions comply with applicable United States , international, and in some cases host-nation laws and regulations. Commanders at all levels ensure that their Soldiers operate in accordance with the law of war and rules of engagement. (See FM 6-27.) ATP uses joint terms where applicable. Selected joint and army terms and definitions appear in both the glossary and the text. Terms for which ATP is the proponent publication (the authority) are marked with an asterisk (*) in the glossary.
