Final answer:
The specific 3 stages of team development according to FM 6-22 are not provided in the materials, thus an accurate response reflecting those specific stages cannot be given.
Step-by-step explanation:
The 3 stages of team development per FM 6-22, which pertains to the Field Manual on Army Leadership, are not directly listed in the provided material. However, referring to commonly recognized models of team development, such as Bruce Tuckman's theory, we can examine similar stages that teams may go through during development. A widely acknowledged framework comprises the forming, storming, norming, and performing phases, but these do not directly correspond to FM 6-22, which may have different terminologies or concepts for team development. The provided passages enumerate various phases and stages of different developmental processes and types of teams, but they do not directly align with the FM 6-22 stages for team development. Therefore, without the exact text of FM 6-22, we cannot confidently determine the specific three stages of team development referred to in the question.
