The Army has surpassed the Navy in terms of the number of cases, with 3,836 as of Thursday, compared to 3,662.
COVID-19 has claimed the lives of three service members since the pandemic began.
According to Johns Hopkins University's running totals, there have been at least 2.7 million cases of COVID-19 in the United States, with 128,651 deaths.
Pentagon officials say the increase in cases at military installations happened in areas seeing increased case counts among the civilian population.

McCaffery also said the military is increasing testing for individuals who do not have symptoms.
