明文規定軍人必須服從上級的命令，否則就是違背誓言！違背入伍誓詞是會被以軍法處置的！美國軍人入伍誓詞：我，XXX，謹莊嚴宣誓（或鄭重聲明），我將支持並保衛美國憲法，抵抗所有國內外敵人；我將對憲法保持真誠的信念與忠誠；我將依照法規和《軍事司法統一法典》，服從美國總統的命令，並服從上級軍官的命令。願上帝幫助我！美國軍方（DoD）現行版本的入伍誓詞內容為（來源：10 U.S. Code § 502）：I, ___, do solemnly swear (or affirm) that I will support and defend the Constitution of the United States against all enemies, foreign and domestic; that I will bear true faith and allegiance to the same; and that I will obey the orders of the President of the United States and the orders of the officers appointed over me, according to regulations and the Uniform Code of Military Justice. So help me God.
