Manning's statement came in response to comments by Air Force Gen. Terrence O'Shaughnessy that some of the troops being sent to the border will be armed. But they do that with us, they're going to be arrested for a long time.
Soldiers from the 97th Military Police Brigade, and 41st Engineering work along side with U.S. Customs and Border Protection at Hidalgo, TX applying 300M of barbed wire in support of Operation Faithful Patriot.
But Operation Faithful Patriot is meant to be a mission where the active duty troops are only to provide support for CBP since they are forbidden by federal law to carry out law enforcement duties.
Chairman of the Joint Chiefs of Staff Gen. Joseph Dunford told reporters Monday that USA troops deployed to the southern border are there to assist the Department of Homeland Security, and not "the actual mission of denying people entry to the United States".
By voicing its opposition, the Pentagon helped ensure that its mission was tailored to only providing support to USA government personnel on the border, US officials said.

Manning noted that DHS had requested that active duty troops, rather than reservists - who usually partake in operations on United States soil - for this operation.
According to the New York Post, "The soldiers worked with US Customs and Border Patrol officers to lay about 1,000 feet of fencing along the river, the Defense Department said".
Trump said last week that rocks thrown by immigrants should be considered a firearm, and that the military would fight back.
The officials said that while there had been informal talks between the Department of Defense and DHS about having the military build tent facilities to house detained migrants, tents were never part of the formal request for assistance submitted by DHS and approved by Secretary of Defense Jim Mattis. DOD officials studied the request and proposed what is being deployed now. Instead, the tents will serve as temporary shelters for border security reinforcements. DOD was tasked to provide logistical and medical support.
Asked about the cost of the operation, Manning said it had yet to be determined by the Pentagon's financial services.
Reuters was first to report that the Pentagon had balked at the initial request from the Department of Homeland Security.
