In the United Kingdom (UK), the Parliamentary Defence Committee has conducted an inquiry into the efficacy and efficiency of military deployments during the COVID-19 pandemic.

The Committee's review examined: the Ministry of Defence's planning and preparedness for a pandemic; how the armed forces supported civilian authorities during the pandemic; and the effectiveness of specific actions and activities undertaken by military and civilian personnel during the pandemic. Inquires such as this help ensure that security sector institutions are used and funded in a way that is efficient and effectual.
