Pentagon says no.
On the basis of the request, two security officers said the Department of Homeland Security called for the Pentagon to become a reserve force that could be called to "crowd and traffic control" and to protect its border guard and border guard personnel against a group in Central America migrants who are on the US border to seek refuge.
The Pentagon rejected the request on 26 October, according to one official, even when DHS was signed with aerial and logistical support, medical staff and engineers.
The request was rejected because the Ministry of Defense felt that active soldiers did not have the power to carry out such missions unless the president issues additional authority.
Defense officials have repeatedly stressed that border troops support civilian authorities and are not expected to have any contact with migrants.
Despite the fact that several security officers who have described these activities in conjunction with law enforcement activities, DHS's official view is that such tasks do not involve law enforcement.
"While DHS discussed the need for the potential for strong protection of CBP staff," law enforcement activities "said this support item incorrectly," DHS said.
"Quick and Long"
During the White House speech in Thursday, the chairman suggested that the troops should be fired on immigrants by throwing rocks, saying that rocks are considered as rifles and that the group of about 3,000 men, women and children must be seen as "invasion".
On Friday, Trump tried to hold back these comments and told reporters that "if our troops, or the border guards or the immigration and customs officers officers" were hit, we will keep these people. This does not mean shooting them, but we are arresting people for a long time and a long time.
Defense Officers describe that DHS is requested as a tool that can only be used if the CPB's staff is overwhelmed by the situation at the border.
Nevertheless, the Pentagon rejected the reserve defense request while simultaneously approving DHS's all further support requests with the approval of the Defense Minister James Mattis. It is unclear whether Mattis has considered the decision to reject the teams' request for law enforcement duties.
The first defense officer said that in his response to DHS, the Department of Defense stated that if security officers continue to want US troops to reserve, they must ask the White House to officially authorize the Pentagon for additional functions to the authorities.
Customs and Border Protection refused to comment.
Kirsten Nielsen, the home security minister at Fox News, said last week that DHS asked for air, engineers, logistics and planning support, as well as vehicle constraints and "ways to protect its officials and agents and port you enter. "
The Posse Comitatus Act prohibits the US Army from enforcing domestic laws unless there is no other choice. Military analysts say Trump can easily use the National Guard, US Marshals or Immigration and Customs Personnel Officers if needed to support border guards.
Costs of the operation
More than 8,000 active soldiers may be deployed to the southwestern border than they are in the most controversial combat zones in the world, but only support domestic security officials when they are ready for immigration.
Between 2011 and 2015, President of Cabinet Chiefs Martin Dempsey, a retired general, sent a message Friday that "uniformed men and women are better qualified, better equipped, and better guided to meet the threats." The wasteful deployment of excessively stretched soldiers and Marines is much worse if they use the disproportionately high power they are facing.
The Pentagon has yet to determine the cost of the operation and did not identify the account where the funding would come from. But the Strategic and Budget Evaluation Center estimates that the cost of placing active soldiers on the border is 42 million 110 million dollars.
CSBA says that at the highest peak, the installation cost $ 143 a day for operating and maintenance costs and $ 112 a day at the lowest level. CSBA estimates that the use of military aircraft in this installation would cost $ 136,645 per day.
For a 41-day mission from 5 November to 15 December, the cost of 8,000 soldiers and aviation support is estimated at about $ 42 million to $ 55 million, according to CSBA estimates.
On Thursday, Trump claimed that the army placed thousands of tents for retention of immigrants, but officials say there is no plan to build tents. Officials claimed that while there was an informal meeting between the Ministry of Defense and the DHS about detained detainees with military construction tents, tents were never part of the formal request for assistance submitted by DHS, and was approved by Defense Secretary Jim Mattis. An official claims DHS informally did not like the defense department's request.
clarification: This story was updated to make it clear that the officials of the Ministry of Defense considered the request as an illegal act. The Department of Homeland Security disputes this characterization and updated the story with DHS's comments.
