For decades, the U.S. southwest border has been vulnerable to cross-border illegal activity such as illegal entries, smuggling of drugs and contraband, and terrorist activities. Since 2002, DOD has supported DHSs mission to secure the nations borders and episodically supported its efforts to manage surges in foreign nationals without valid travel documents who are seeking entry - most recently since April 2018, when the President directed the Secretary of Defense to support DHS in securing the southwest border. GAO was asked to examine this support. This report assesses the extent to which 1 DOD has evaluated DHSs RFAs, 2 DOD has reported to Congress the full costs of its support, and 3 DOD and DHS have collaborated on border security operations. GAO reviewed RFAs that DHS submitted to DOD between April 2018 and March 2020 and a nongeneralizable sample of decision packages that DOD prepared in response, and conducted four site visits to border locations where military personnel were stationed.
