United States. War Department, Manual for Noncommissioned Officers and Privates of Infantry of the Army of the United States…
“ Loyalty means that you are for your organization and its officers and noncommissioned officers--not against them; that you always extend your most earnest and hearty support to those in authority. No soldier is a loyal soldier who is a knocker or a grumbler or a shirker. Just one man of this class in a company breeds discontent and dissatisfaction among many others. You should, therefore, not only guard against doing such things yourself but should discourage such actions among any of your comrades. ”
