I'll just pop in as someone who is married to a sailor (Seabee in the USN).
There are plenty of men and women serving who aren't great people, or who don't conduct themselves well. There are also plenty of people who are great and who hold themselves to a higher standard. Just like there are plenty of bad cops and plenty of good cops. They're still people. They still have their own personalities and vices.
The sacrifices made are real, for both the solider and their family and friends. I am lucky enough that my husband is on a set deployment rotation and is also on a "peacetime" deployment. No combat anywhere near him at the moment. This is hard enough as it is, I can't imagine if he where actually in a combat area. Not everyone is so lucky.
The bureaucracy and red tape in the military is
extremely frustrating. It is definitely a government organization and I don't mean that in a good way. But these soldiers and sailors and airmen...they're not a part of that. They are men and women putting themselves, and their loved ones, second so that they are fit, ready, and able to serve said government and the citizens of the United States. Whether what the government uses them for is good, necessary or right, THAT is up for debate. That does not lessen the respect that I have for their sacrifices and service.
(I don't LIKE every servicemen I come across, and I may not respect them as an individual, but I do respect their service. If that makes any sense at all.)
I do, however, get a little annoyed when people just parrot out, "Thank you for your service!" when they see a uniform. My initial thought response is, "Do you even know what you're thanking them for? Do you even care? Do you really, truly appreciate everything that they've been through in order to be where they are today?"
All in all, basically, this:
I will criticize the US government, it's motives, and the military industrial complex that is alive and well in the US all day long. However, I will support the men and women who go over there in whatever way possible, and I assure you as the step sister of someone who has been risking his life for his country since the age of 18, that support is anything but blind.
