The U.S. Border Patrol late last month warned landowners in Texas to expect "possible armed civilians" to come onto their property because of the caravan, The Associated Press reported.
The supposed request was made at the time when a migrant caravan of mostly Central American asylum-seekers are heading to the United States in the hope to cross into the country.
Far from stopping a tide of tired refugees with cruel live fire, USA troops sent to the southern border aren't even supposed to come into physical with caravan migrants, says Chairman of the Joint Chiefs of Staff Gen. Joseph Dunford.
US Army soldiers install a barbed wire fence along Anzalduas International Bridge near the US- Mexico border in McAllen, Texas, November 5, 2018.
Indeed, these four caravans now are traveling inside Mexico, totaling some 12,000 Central American migrants, as a separate Fox News report indicated on Sunday and as other outlets have noted.
"The requests that we have from the Department of Homeland Security and CBP (Customs and Border Protection) is to build (facilities) to support CBP personnel and our military personnel", he said.
"Our military will not receive combat pay or hostile-fire pay as they are not deploying to a combat area, nor are they expected to be subject to hostile fire", he said, adding that they will be eligible for a separation allowance.
"Barbed wire looks like it's going to be very effective, too, with soldiers standing in front of it", Trump told a campaign rally in Cleveland.
Customs and Border Protection declined to comment. But the Center for Strategic and Budgetary Assessments estimates that the cost of placing active duty troops on the border could range from $42 million to $110 million.
The chairman of the Joint Chiefs of Staff spoke out Monday against several retired generals who have criticized the recent deployment of active-duty troops to the southwest border, countering that us military leaders are following a "legal order" from President Donald Trump. The border mission is considered non-combative, Manning said.
The troops are being deployed as a migrant caravan makes its way north to the USA border. The administration says it needs to harden border security as the Central American caravan heads north.
However, Trump's effort has been embraced by Republicans running in the elections, in which illegal immigration is a top issue.
