Here's a quote from wikipediahttp://en.wikipedia.org/wiki/Jesse_Ventura
From September 11, 1969 to September 10, 1975, during the Vietnam War era, Ventura served in the United States Navy. While on active duty, Ventura was part of Underwater Demolition Team 12 (UDT). The UDTs were merged with the US Navy SEALs in 1983, 8 years after Ventura had left the Navy. Compared to SEAL units, UDTs saw less combat, and took fewer casualties.
Bill Salisbury, an attorney in San Diego and a former Navy SEAL officer, accused Ventura of "pretending" to be a SEAL and wrote Ventura would be blurring an important distinction by claiming to be a SEAL when he was actually a frogman with the UDT.  Following that, Governor Ventura's office confirmed that Ventura was never a member of the SEALs. His spokesman stated that Ventura has never tried to convince people otherwise Ventura stated: "Today we refer to all of us as SEALs, that's all it is."
Ventura has frequently referred to his military career in public statements and debates. He was criticized by hunters and conservationists for stating in an interview with the Minneapolis StarTribune in April of 2001 he said "Until you have hunted men, you haven't hunted yet."
In January 2002, Ventura, who had never specifically claimed to have fought in Vietnam, disclosed for the first time that he did not see combat. He did not receive the Combat Action Ribbon, which was awarded to those involved in a firefight or who went on clandestine or special operations where the risk of enemy fire was great or expected."
Now personaly I wouldn't judge a man on that figure of speech when his proffesion demands sound bites.
How long does it take to explain the difference between being a
Navy SEAL and being in a unit which is now called 'The Navy SEALS'?
If he was discussing it over a nice cup of tea I'd expect that kind of detail, but in the confrontational side of American media, I thought that would be OK for a bit of chest beating.
Edited to add that I'm sorry if my take on that looks moronic.
It's not my intention to stereotype or to cheapen Navy SEAL's military honours.
