I'm going to say something as a veteran that is unpopular and even dangerous to say, but I'm going to say it now anyway.
There are A LOT of veterans who have filed false claims for disability benefits that otherwise clog up the VA system with bullshit.
I know a "veteran" who served his contract time in the Army and as he was separating from service claimed he got asthma from the Army. He was an IT guy in uniform. That led to a follow-on claim for back injury as service connected, but he wasn't airborne, wasn't infantry, etc. He was a communications guy. Today this same guy is at minimum 100+ pounds overweight, smokes like a chimney, and YOU and I are paying for mounds of services and medication for this guy in addition to his LIFELONG disability check from the VA.
I know another guy who served his 5-year contract with a congential defect of his foot (club foot). Somehow he managed to make it into the Army that way and when he left was able to claim it as a service connected disability. From talking to people he served with he was unable to perform his full range of duties from the beginning and ended up being assigned to desk jobs for his entire 5-year enlistment. Yep, we pay him close to $1,700/month in disability for something he was born with. He had the audacity to tell me one day "Dude, you gotta get some of this VA benefit! There's gotta be something wrong with you?"
I know another guy who served a garrison tour for 3-4 years in Korea and then got out. Some 20+ years later he filed a compensation claim for bad knees, the VA awarded the claim and the VA just replaced his knee. He too is overweight, but has NOTHING to reflect any high optempo, highly physical periods of service that would have damaged his knees when he was in his early 20's over 20 years ago. BUT, you and I are paying for the medical bills and the disability check he gets now.
I can go on and on. I've watched at VA reps brief Soldiers returning home on all the ways they can in effect submit fraudulent claims and how they are ENTITLED to disability compensation and medical benefits simply from serving. It's bullshit and it's part of the problem. They tried to tell my Soldiers after we did police work here in the states that we absolutely should file a disability claim for lower back issues because we had to sit in a patrol car for 8+ hours a day with our police equipment belt and body armor on and that although we didn't know it now, our backs were irreparably damaged. WTF?!?!
