Being in the US military isn't all that dangerous compared to other dangerous jobs. Only 7000 or so depending on who you ask have died in the last 20 years. That includes two wars, one that lasted 15 years.
Yeah PTSD is for real., I'm not discounting the nature of the military. But you probably aren't going to die. The US military should do better when those folks no doubt, but on the whole most benefit from their active duty.
Construction too. I peg my "I'm in danger" meter every time I go up in a scissor lift. Those lights/speakers/fire strobes/WAPs don't make it 30 feet up to your Walmart ceiling by themselves. Then there's the residential a-hole who wants a camera at the apex of his roof on the third floor, so gotta break out the creaky old sun-bleached 40-foot extension ladder and fuck around like Clark Griswold...
Truth. I just retired from the US Air Force 2 years ago. Spent 20 years as an IT technician. Most of the time, I just worked in a safe, secluded server room. Even while deployed to Iraq, I pretty much worked and lived in bunkers. Wasn't even allowed to leave the base. My job was pretty safe.
I deployed to a Marine camp once in 2005. My Marine boss said she hoped to god she never saw an Air Force person with a gun in their hands. She said that would mean the planes are down, the base is overrun, and the Marines are dead. She said we were literally the last line of defense. So if we were ever attacked, she told me to just hand my weapon and ammunition to the nearest Marine and go take cover until it's all over.
