Final answer:
The two PRT formations are the extended rectangular formation, typically used for addressing personnel and conducting calisthenics, and the circular formation, which is better suited for stationary or strength training exercises.
Step-by-step explanation:
The term PRT formations typically refers to Physical Readiness Training formations, which are used in the military to organize personnel for physical training exercises. There are two primary formations used in PRT: the extended rectangular formation and the circular formation.
Extended Rectangular Formation
This formation is often used when the leader needs to address a large number of personnel or when conducting calisthenics and other drill movements. It offers good control for the leader and allows all participants to see and follow instructions.
Circular Formation
The circular formation is used for stationary or strength training exercises where the participants need to be closer together for instruction or mutual support. It's ideal for smaller units or groups where interaction during the training is beneficial.
