Unlike other special-operations units, the SEALs went through a different level of combat diving training to prepare themselves for any underwater special operations. The SEALs did not only train to travel in the water but to conduct underwater missions too. The potential conflict in the Pacific has pushed officials to give SEALs a more rigorous training, considering that the team is the only special-operations unit tasked with underwater special operations. In addition to the traditional combat diving operations, the SEAL Teams also has the SEAL Delivery Vehicle (SDV) capability manned by SEALs who went through an even more extensive training.
