I think we can skip the "support" piece of your comment as NightTrain has taken care of that (thanks dude!). I do want to clarify that, and you won't understand this unless you have actually SERVED in the military, but it is against regulations to disobey the orders of, or even speak poorly, of the commander in chief. He is the top of your chain of command. Out of uniform you can say you want to vote for Romney, but even on your day off if you go around talking bad about Obama you can be brought up on charges under the UCMJ. I lived in those rank for 21 years...they see Obama's actions and understand them.
Did you see his speech in Fort Bliss earlier this year? The Soldiers behind him hardly clapped because they know what type of President he has been.
On to the disgraced part...
From my view, as someone who has given more to this country than most, Obama going around apologizing for America and undermining our influence is a disgrace to the office. The fact that a sitting president would notify the enemy "hey, we are calling it quits on Dec 31, 2013" limits the ability for commanders on the ground to shape their battlespace and accomplish their mission. I agree we should pull out, but do so based on conditions on the ground...not based on a calendar! If we are now scheduling wars, I want to know when the next one starts.
I could list more but you probably won't care...so there you go.
