Opportunity training is commonly referred to as what?

Opportunity training is widely recognized as "Hip Pocket training," which refers to informal, on-the-job training that is typically spontaneous and often presented in the field. This type of training is designed to make use of immediate, real-world scenarios where soldiers can gain practical experience and learn from their leaders or peers. It emphasizes learning through doing, allowing soldiers to develop skills in a hands-on manner without the need for a structured classroom environment.

This approach is beneficial because it equips soldiers with the necessary skills and knowledge in a timely manner, often just when they need it. It utilizes the immediate environment and the expertise available within the unit, making training relevant and applicable to the soldier's current duties. By focusing on practical application, hip pocket training enhances retention of information and skills, fostering a stronger capability within the unit.

The other options reflect different types of training that do not capture the essence of opportunity training. For instance, formal training usually involves a structured curriculum and is often conducted in a classroom setting, while structured training similarly follows a designed plan. On-the-job training, while related, is typically more formalized than hip pocket training and not as spontaneous. Therefore, "Hip Pocket training" is the term that best encompasses the flexible and immediate nature of opportunity training.
