The Pentagon has already shot down suggestions the troop deployment was politically motivated and said the name was chosen by the US Northern Command.
Earlier this week, Reuters reported that the Trump administration discussed using the usa military to build facilities to house detained migrants as part of its mission on the Mexican border, but the idea was dropped after the Pentagon expressed doubts about it.
However, that official also said it couldn't be denied that phrase "Operation Faithful Patriot" had potential political overtones.
The deployment of troops was deemed necessary in view of a caravan of several thousand migrants approaching the USA border. Travelling from Guatemala and Honduras, the migrants seek a better life on USA soil, while the U.S. government says the caravan will bring in more criminals and people of non-Central American nationalities.
Pentagon spokesman Lt. Col. Jamie Davis said in a statement on Wednesday that the U.S. Department of Defense was dropping the name, but added that although it would no longer be called "Operation Faithful Patriot", the operation was still named and still ongoing.
The Wall Street Journal first reported the name change and that the decision was made by Defense Secretary James Mattis's office, which issued the order on Election Day, according to officials.
It is speculated that the border deployment is not actually an "operation", since "operations", in Pentagon jargon, are full-fledged combat missions.
According to reports from earlier this week, the soldiers will not directly interact with the immigrants.
"We don't do stunts in this department", Mattis told reporters. "We are providing enabling capability".
Pentagon officials rolled out the name last month after President Donald Trump ordered thousands of active duty troops to the southwest border in response to a caravan of migrant families walking slowly north through Mexico toward the U.S.
