Veterans should not have the right of free speech?
No, we do not. We gave that up when we joined the military.
And yes, other parts have been taken since then. For example, President Clinton threw multiple "Blanket Gag Orders" at the military, and many of them have since become accepted part of standing military orders. For example, I can no longer write to a news paper or call a radio show and make statements critical against the President or his policies. And this continues to this day. A lot of people acted shocked when Military Clergy in the military were forbidden from commenting on certain government policies. This is nothing new, such "Executive Gag Orders" have gone out countless times, forbidding Chaplains from talking about things from abortion to homosexuals. And these orders have extended to the members of the military as well, forbidding them form participating in "letter writing campaigns" to political officials.
I am sorry, but you are a civilian, so probably have never cared about such things before in your life, so you never knew they existed. To us, they are simply a routine part of our life.
How does that negate the responsibility of his commanders not to place him in harms way unnecessarily?
That is the purpose of the military. It is our job to go into harm's way, so hopefully others will not have to.
And oh how I love that last word you put in there. "Unnessarily". What does that mean? Well, it means almost anything you want it to mean.
How here is the dirty truth of military operations: Military commanders are suppposed to expend the lives of those that serve under them. In fact, if they do not do so then they are in dereliction of their duties. But the decision must be done as to accomplish the goal of the mission, or to save the lives of others.
Sometimes military commanders make hard decisions in moments. You send out a platoon, in the hopes that it gets ambushed by a company sized unit. Yes, you may loose the entire platoon, but following back that company sized unit may lead you to a Battalion that you can then eliminate with much lighter losses. And that kind of decision happens all the time. Ask any grunt about "Single Envelopment Drills".
But it is our job to go into harms way, often unneccessarily. We were heading down freeways into a hurricane not to many years ago, because people needed help. Our pilots took off to do mission after mission to try and cool a reactor that had melted down, each and every mission taking higher and higher doses of radiation. And one of the leading research organizations is USAMRIID, which does things like rushes personnel to Africa whenever there is an ourbreak of something like Ebola.
