In the United States Army Special Forces, the motto is traditionally believed to mean "to free from oppression" or "to liberate the oppressed" in Latin.[1]
Actual translation
A correct translation of the Latin phrase de oppresso liber would be "from (being) an oppressed man, (to being) a free one".
Grammatical structure
The preposition de here means "from" in the sense of a change from one status to another,[2] not intending separation from the oppressed, but moving from a source in the oppressed.[3] Compare Ovid Fasti 5, 616: inque deum de bove versus erat, "he had been changed from an ox into a god", or Juvenal 7, 197: fies de rhetore consul, "from an orator you will become a consul". Oppresso is the past participle of opprimere ("to oppress") in the ablative case as governed by de, meaning "an oppressed person". The adjective Liber is in the nominative case, "a free person".
Similar phrases
The motto resembles a quote from St. Augustine:[4]corripiendi sunt inquieti, [...] oppressi liberandi, "the turbulent have to be corrected, [...] the oppressed to be liberated". See also Isaiah 1:17: subvenite oppresso, "relieve the oppressed".
The sculpture America's Response Monument is subtitled De Oppresso Liber. It is a life-and-a-half scale bronze statue located in the West Street lobby of One World Financial Center opposite Ground Zero in New York City. Unofficially known as the Horse Soldier Statue, it is the first public monument[5] dedicated to the United States Special Forces and commemorates the servicemen and women of America's Special Operations response to 9/11, including those who fought in the early days of Operation Enduring Freedom, which led to the initial defeat of the Taliban in Afghanistan. It was conceived by a private citizen, sculptor Douwe Blumberg, and commissioned by an anonymous group of Wall Street bankers who lost friends in the 9/11 attacks.
