Why are Airmen 3-4X more likely to commit suicide than the civilian population when the Air Force screens for risk factors prior to entry?

Common risk factor include:

Mental Health Issues
Criminal History
Substance Abuse Disorder
History of Abuse
Financial Issues

You might recognize these, because they are exactly what the military looks for before letting someone enlist/commission. Our suicide rate is equivalent to the prison population of the US (.04%), and 4X higher than the US suicide rate (.01%). If we are screening for these issues, shouldn’t we theoretically have a lower suicide rate than the civilian population? How do we have the same numbers as the prison population which consists of nothing but risk factors? I believe the common public outlook on military suicide is that it is largely due to combat stress or PTSD. However, we are having our highest numbers in peacetime. What would our suicide rate look like without screening?

Most interestingly, our training almost always paints the signs (social withdrawal, marital issues, alcohol abuse) as being tied to the individual, and not the military as a whole. I hadn’t realized this until a fellow NCO talked about it during an open discussion. He shared with us that he went through a period of time himself many years ago where he was contemplating suicide. He said: “Sitting through this training does even more damage for an Airman because it paints this issue as a problem with them, not a problem with our culture and environment. Like they’re somehow defective and everything is A-okay with the way things are going around them.”
