Blue, Green, Tan, or White
We all are part of the same damn fight.
Basically what this means is there is no unimportant job, and that all military servicemen and women past, present, and future, regardless of branch of service, specialty, or reason for enlistment have indeed volunteered for a profession knowing that someone could attempt to end their life prematurely. Simply put if it were not for the Non Combat roles (I.e. Logistics, Medical, etc.) the combat roles (I.e. Infantry, Armored, etc.) would be far less effective at completing our missions. After all a military moves on it's belly. (paraphrased from Julius Caesars' quotes).
BTW U.S. Army 11B HOO-AH!
