"The purpose is to make sure that we're not bringing the virus back home, infecting others, that we're not spreading it around the military," Esper said.Esper said one exception to the order would be the drawdown under way in Afghanistan, which will continue.The United States has said it is committed to reducing the number of its troops in Afghanistan to 8,600 within 135 days of signing the deal with the Taliban last month.
The US military said earlier on Wednesday it was also elevating its health-related security level at bases worldwide because of the spread of the coronavirus, as it acknowledged the persistent growth in the rate of infections across the force.
