FYI, Rigel, I was a patriotic and dedicated volunteer from just before the Nam war kicked off and, when it did, my first, second, and third choices for duty assignments were to go to Nam. I had listened to each and every live speech of JFK's evening broadcasts via TV and radio and what impressed me most was his words, "Ask not what your country can do for you, but what you can do for your country." When men and women today volunteer for service in the armed forces and enlist, yes, they most certainly do begin as recruits and go through recruit training (see http://www.bootcamp.navy.mil/). Furthermore, I had dearly wanted to enlist in a six-year program to serve aboard a nuclear sub (notwithstanding news of the USS Thresher in 1963) and later, at NAS Millington, spoke with a SEAL recruiter to enlist in that program. On both counts, my less than 20/20 eyesight disqualified me.
If you, Rigel, were keeping in touch with the "Early Bird Briefs" published daily by the editors of Defense News and Military Times as I do each morning, you would see a different picture of today's military than what you suggest. It is reported that military personnel today tend to be generally overweight and ofttimes even obese to the point of alarming senior defense officials (see https://www.militarytimes.com/off-duty/military-culture/2018/10/03/a-staggering-number-of-troops-are-fat-and-tired-report-says/). They do not always "work as a team" among their sometimes overbearing peers and commanding officers who are similarly out of touch and unfit to command. Such reports are not isolated or infrequent. Many of the team I worked with in my former squadron I remain in close contact with today as brothers.
Technology I worked with in the '60s was state of the art in its day and will soon outdate current technology and we were just as dedicated to our tasks as any servicemen of our time could be and as were so many other volunteers in all wars fought. There were occasions when I worked well beyond my twelve-hour shift aboard ship to repair and sign off maintenance on a plane in time to get it into a pending strike cycle and see it armed, fueled, and sent aloft. In 2010, I made a personal pilgrimage to visit and honor the shrine of those seamen killed aboard the USS Cole at NAS Oceana at Virginia Beach.
It appears you, Rigel, are grossly out of touch with the reality of the times and your actual "knowledge" seems very limited. You really need to re-educate yourself and I suggest you start here: https://www.militarytimes.com/ebb/ and learn to separate fact from fiction.
