Former Secretary of Defense Leon Panetta. Screenshot via MSNBC President Donald Trump ruffled some feathers on Thursday with his choice of words when describing an overseas military operation.

The comments came when a White House press pool reporter asked Trump if he had personally authorized the deployment of the 21,000-pound bomb that was dropped on an ISIS tunnel complex.

"Everybody knows exactly what happened. What I do is I authorize my military," Trump said. "We have the greatest military in the world and they've done a job as usual. So we have given them total authorization."

The phrase "my military" stuck out to members of the defense community, some of whom did not appreciate Trump's use of the possessive pronoun. Chief among them was Leon Panetta, a former defense secretary and CIA director who served under President Barack Obama.

"When it comes to the military, the military belongs to the country. Our defense system belongs to the country. And it's not the president's military, it's the military of the United States of America," Panetta said on MSNBC's "Hardball with Chris Matthews."

"He has responsibility obviously, as commander in chief, to be able to make decisions with regards to our military. But I think if you ask the men and women in uniform who they are responsible to, I think their answer would be, 'We're responsible to the United States of America.'"
