Creating adaptability in Soldiers is an Army Chief of Staff strategic priority and a critical requirement for the future Army. The purpose of this paper is to make a recommendation to create adaptability in the current Army training system through initial research of behavior performance measures and then embed the results into the training system. Arguably, the Army training system produces some level of adaptability as a byproduct of producing ready units. However, adaptability performance behaviors are too critical to leave to chance creation. To address this imbalance, the Army needs to be deliberate in its goal to increase adaptability through the existing training system. Defining adaptability’s trainable aspects and understanding how the Army trains are the first steps in determining how to change current mechanisms to create a system that fosters purpose-driven adaptability. The tasks trained in the system are the key to driving adaptability behavior change in the Soldiers tasked to win in a complex world.
