The teams started in WWIi aka frogmen. They have been involved in every theater of operations! They have been spilling their blood for every president since Roosevelt! JFK, made the official! They have been re-organized every twenty years. There are a few teams out there, each with their own specialty. They all start the same, but go in different ways out of Coronado island. They all deserve praise and admiration! These are the ops we here about. There are craploads more we don't. It's about time they get dome recognition. Many have gone without a tear from the general public. I could also tell you they do not fo it for anything else except to be the best of the best! Sorry for the tirade!
