As the COVID-19 pandemic has unfolded, Congress has considered how the Department of Defense (DOD) might support the U.S. government's domestic response. Below are the funding, authorities, and descriptions of potential ways DOD might further contribute. Links in this product connect to more detailed information on the highlighted subjects.

President Donald J. Trump declared a U.S. national emergency on March 13, 2020. On Friday, March 20, the Federal Emergency Management Agency assumed the lead agency role in the Coronavirus Task Force under the National Response Framework (NRF) for national emergencies. DOD participates in the national response within the NRF. For more information on the domestic and international health aspects of COVID-19, see CRS Report R46219, Overview of U.S. Domestic Response to Coronavirus Disease 2019 (COVID-19), and CRS In Focus IF11421, COVID-19: Global Implications and Responses.

Defense Funding

The Families First Coronavirus Response Act (P.L. 116-127) became law on March 18, 2020. Title II of Division A of the act included $82 million for the Defense Health Program to waive all TRICARE cost-sharing requirements related to COVID-19.

The Coronavirus Aid, Relief, and Economic Security Act (CARES Act; P.L. 116-136) became law on March 27, 2020. Title III of Division B of the act includes $10.5 billion in emergency funding for DOD.

Of the $10.5 billion, $4.9 billion (47%) is for the Defense Health Program (DHP), according to the bill text. The DHP funding includes $1.8 billion for patient care and procurement of medical and protective equipment; $1.6 billion to increase capacity in military treatment facilities; $1.1 billion for private-sector care; and $415 million to develop vaccines and to procure diagnostic tests, according to a summary released by the Senate Appropriations Committee. H.R. 748 also provides:

Defense Capabilities and Authorities

DOD has capabilities that can directly support civil authorities in health emergency situations, including health and medical surveillance, research on diseases, treatment facilities, communications equipment, temporary lodging facilities and storage space, material-handling equipment, and logistics support. Installations approved for these purposes include Active and Reserve Component bases. This type of assistance is called Defense Support of Civil Authorities (DSCA). For more on DSCA in the COVID response see CRS Insight IN11305, COVID-19: Defense Support of Civil Authorities, by Lawrence Kapp and Alan Ott and see CRS In Focus IF11483, The National Guard in the COVID-19 Pandemic Response: Framework for Action, by Alan Ott.

Integrating Defense Capabilities

Currently, legal authority for DOD involvement in domestic disasters is provided in the following statutes.

Reserve Component Activation

On March 22, the President authorized activation of National Guard personnel in hardest-hit states of New York, Washington, and California under Title 32 U.S.C. §502(f), which allows governors to control operations with pay and benefits provided by the federal government. The President could also order the National Guard and Reserves to federal active duty under Title 10; applicable authorities include

A state's governor can also activate its National Guard for full-time state duty (i.e., state active duty); in this status, pay and benefits are determined by state law. For more on Reserve Component activation, see CRS In Focus IF10540, Defense Primer: Reserve Forces.

U.S. Army Corps of Engineers (USACE)

Per historical precedent, USACE involvement in rehabilitating or constructing facilities as part of a domestic disaster response under the National Response Framework would be funded through the Disaster Relief Fund (DRF), not from DOD funds. In this situation, the federal lead for the disaster would assign a task to USACE and pay for the task through the DRF. Below is an excerpt from the NRF that describes the typical assignment for USACE's largely civilian staff.

Defense Production Act

As the COVID-19 pandemic evolves, the United States faces scarcities due to disrupted supply chains and increased demand for drugs and medical supplies. In response, the President may invoke emergency authorities under the Defense Production Act of 1950 (DPA; 50 U.S.C. §§4501 et seq.) to address economic impacts. He did so on March 18, 2020, through an executive order but has yet to give direction to the private sector under this authority. For more on the DPA, see CRS Insight IN11231, The Defense Production Act (DPA) and COVID-19: Key Authorities and Policy Considerations, and CRS Report R43767, The Defense Production Act of 1950: History, Authorities, and Considerations for Congress, by Michael H. Cecire and Heidi M. Peters.
