Don't go moving the goal posts now. Any position of authority is backed by some level of force whether it be political, financial, physical etc.

position of FORCE, means you physically intimidate somebody and are in a
position to inflict bodily harm as part of the job description
The only job description that sounds like is a professional fighter. It damn sure doesn't describe the role of a officer or noncommissioned officer in the US Army.

Being powerful and having control over people by other means is different,
for one thing it requires a brain.
So you don't think people that are law enforcement or in the military (your examples) attained their positions through hard work, intellect and ability or as you put it, have a brain?

For many kids growing up in a certain environment, joining a gang is no
different than slightly more privileged kids joining the military. They do so
for exactly the same reasons
Why do you think privileged kids join the military? Couldn't really be farther from the truth. Most Soldiers come from lower to middle class families. Most join the military to get money for school and/or job training. Some do it simply to get out of small town USA. I don't think that is a big part of the Bloods and Crips recruitment pitch. You make a lot of sweeping generalizations about people and things you don't seem to know much about.
