And that is usually when an active war is going on.
Even when an active war is on, those in charge have learned to limit the length of time a soldier spends in warzone to 1 year. Like US did in Vietnam war.
For cop in certain areas, they are exposed to loving life/limb any day. It may happen only once a year or just a few years. But still, I wouldn't say one can be a cop only if you are willing to lose own life.
Soldiers can easily get a lot more than one year of combat time. How many full time soldiers only do a single tour in Iraq or Afghanistan?
The stats show policing isn't that dangerous. Most cops never need to draw their weapons. If you want to see a dangerous job look at crab fishing.
But for US cops, any chance encounter on the street can be deadly. And that lasts for their entire career.
I have trouble with agreeing with someone who says that a cop should be ready to give up life during their whole career of 30 + years.
Meanwhile SWAT details (particularly in medium sized cities with more toys than mandatory training) are going to consistently attract the worst of the so called "bad apples" from the greater ranks of police. Individuals that joined up specifically because the rough and tumble stuff appealed to them.
This is absolutely false. It may have been true in Vietnam, but that has to do more with there being a near infinite source of soldiers (the draft) and also an insane amount of soldiers being killed an maimed and unable to take a 2nd term.
In Afghanistan and Iraq, I knew people who were serving five or six tours.
