That's not true in the slightest I suggest you go do deeper research or provide something backing that up because there are quite a few examples of convicted criminals serving in the military rather than jail time.You can't join the military with any background related to drugs, theft, or violence. They are actually pretty picky about who they allow in
"•Even though the policy violates military recruiting regulations, US criminal courts have allowed gang members to enter the service as an alternative to incarceration. Several instances wherein gang members have been recruited into the armed services while facing criminal charges or on probation or parole have been documented. In many instances, a gang member facing criminal charges may be provided the option to join the military or serve a jail sentence. Furthermore, some army recruiters have been known to conceal recruits' gang affiliation to help boost their enlistment numbers."
This is well documented and easy to verify.
