The Trump administration has asked military personnel station along the U.S. Mexico border to paint a mile-long stretch of barriers near Calexico, a task that will keep an undisclosed number of troops occupied for at least a month, according to the Hill.
The Department of Homeland Security (DHS) notified Congress of the decision on Wednesday through an email, in which it said the project would lift the aesthetic appeal of the California structures and serve a number of strategic objectives.
In the email, the agency argued that painted barriers would make it harder for border crossers to camouflage, citing a series of recently painted border structures near Tucson. The governmental body also said painted walls would be harder for migrants to climb.
The government has not specified what color the Calexico structures would be painted, but similar barriers along the border have recently been repainted white. Last month, the Washington Post reported that Trump would prefer for the barriers to be painted black since that color would absorb heat and become too hot for migrants to climb.
Customs and Border Protection, the enforcement arm of DHS, will pay for project's paint and equipment, which will cost an estimated $150,000, according to sources quoted by CBS News.
