2-05 Training Formations
Section III. TRAINING AREAS
An advantage of combatives training is that it can be conducted almost anywhere with little preparation of the training area.
2-5. TRAINING FORMATIONS
Formations used for physical training may also be used for combatives training (FM 21-20). If the extended rectangular formation is used, the first and third ranks should face the second and fourth ranks so that each soldier is directly across him a partner.
A large, grassy, outdoor area free of obstructions is suitable for training. Each pair of soldiers should have an 8-foot square training space. When practicing throws or disarming techniques, soldiers need twice the normal interval between ranks. Instructors also pair soldiers according to height and weight.
