What is the difference between the US military elite units?

Navy Seals, Recon Marines, Army Rangers and Army Green Berret?

I know that they are from different branches of the military, but what is the difference between the training they have to go through and the kind of missions they carry out?What is the difference between the US military elite units?You answered your own question. Training is mission based. Each entity has a different mission and therefore they concentrate their training on that mission. Some training will naturally be the same because some of the missions will overlap (i.e. jump school, scuba school etc.). But by and large these units are all high speed low drag and highly motivated or the members in them would not last long.What is the difference between the US military elite units?There are 3 military branches, Navy (the best one), Air Force (for fat ppl), and Army (for dumb ppl), they have their elite units like, Navy: Seals/Spec ops, Army: Special Forces/Rangers, I don't know what the Air Force has I'm guessing a bicycle riding crew. But it takes place of a job, like im a Corpsman in the navy, but if I was a seal, I would be a seal, you get it. Here is a vid of seal training, I trained with them @ BC and I felt like crying, they never stop.What is the difference between the US military elite units?http://en.wikipedia.org/wiki/United_Stat鈥?/a>
