From the report: "Following the riot on the U.S. Capitol on January 6, 2021, reports began to emerge of the seemingly disproportionate role played by current and former members of the U.S. military. Most recent data suggest that 12 percent of those arrested and charged with participation in the riot were current or former members of the U.S. military (Milton and Mines, 2021). In addition, two members of the U.S. Army National Guard contingent charged with protecting the Capitol and the inauguration of President Joseph R. Biden were removed from duty specifically for expressing anti-government sentiments (Schmitt and Cooper, 2021). In April of 2021, Seth Jones and colleagues at the Center for Strategic and International Studies presented data showing that the percentage of terrorist attacks and plots perpetrated by active-duty or reserve service members went from zero in 2018 to more than 6 percent in 2020 (Jones et al., 2021). Anecdotes also abound of active-duty service personnel engaged in extremist activities."
