The correct answer is an unwavering dedication to the success of our conflicts, the advancement of our country, and the strong loyalty to our fellow Marines with whom we engage in combat.
The Corps' motto is "Semper Fidelis" ("Always Faithful"). The fact that there has never been a revolt among American Marines—or even the contemplation of one—is evidence that they have lived up to their credo.
The motto of the Corps was Semper Fidelis, which was chosen about 1883. There had previously been three traditional rather than official mottos. "Fortitudine," which means "With Fortitude," was the first and predated the War of 1812. The second, "By Sea and by Land," was unmistakably a translation of "Per Mare, Per Terram" by the Royal Marines. To the Shores of Tripoli was the third motto up until 1848, honoring O'Bannon's seizure of Derna in 1805.
