Navy SEALs must be able to hold their breath underwater for at least two minutes. In addition, they must perform this feat without producing bubbles.
The Navy SEALS organization is a highly selective. The name comes from the ability to function anywhere: land, sea or air. The training process takes 2 years, and only one-quarter of the soldiers complete the program. They go through a wide range of learning experiences, such as surviving in the Arctic and being hit with tear gas. The most elite SEAL group is Team Six, which is called upon to engage in the highest level cases of special operations.
