BJack: They don't have to be ,it takes thousands of these guys to keep cash in the soldiers pocket.
There may only be one or two out of all of them to know enough for anything to stand up in court if they tried to flip.
This is exactly what they want ,eventually one or two will rise up and become mob prospects. This may take five ten years depending on the made guy.
It is totally different then street gangs or bikers that is is a very short process ,maybe only a year to patch in a bike club.
