The .223 was promoted after a post-WW2 study

showed that most fighting was done within 300 yards

So the theory was that a smaller caliber rifle

would allow soldiers to carry more rounds and be more mobile

the main problem was the AR jammed constantly

required constant cleaning and adjustment

not ideal in a jungle environment
