The point was missed when in the very first post you attempted to compare civilian recreational dive training to military and commercial dive trainings.
I'm just trying to show you how ludicrous it is to even attempt to make such comparisons.
Part of military heightened diving standards is the task load that a military diver has to perform nowadays in war time. That's why military divers, Navy SEALs, Special Forces combat swimmers have to do 10-miles non-finned swims and 30-miles road marches with 100-lbs rucksack.
Tell me where in the civilian recreational dive world where I would have to do anything evenly remotely related to that?
So, yes, military diving standards are different AND more rigorous AND need to be improved with the time because the missions become more dangerous and hazardous. The enemies are wiser about SEALs'/Combat Swimmers' modus operandi, therefore these people have to devise different ways to get to the objectives and execute their missions.
A recreational diver doesn't face any different hazard nowadays than he did 40-years ago. If anything he faces less hazard because of improvement in equipment functionality.
I'm sorry, but where do you get your information? I was in the military for 10 years, and VERY little of what you just said is remotely true (in the United States Military anyway). Military divers are not required to ruck 30 miles as part of their training in Panama City. Even a mortarman or a M-240B gunner typically does not carry a 100 plus pound ruck for over 30 miles. I do not believe that you have ever been in the military, but maybe you have read some articles on the internet or some books? FYI, people do not assault machine gun nests anymore (this isn't 'the big one'), and even Rangers are not trained to shoot whilst hanging upside down from a rappel or fast rope, they are trained to reach the ground safely in an expeditious manner and then engage targets with accurate and controlled fires. You sound like a sea lawyer, either that or you hang out with delta guys all day.
