The United States military deployed about 24,000 troops to help state and local governments across the country fight COVID-19. That mission has ended, at least for now. The Department of Defense is making preparations for the next possible infectious disease spread. And, officials are seeking to learn from the experiences of service members who took part in the COVID-19 mission. The experiences can help military leaders decide on the number and kinds of troops to deploy in case another pandemic or other world crises or conflicts happen, said General Glen VanHerck. He heads the U.S. Northern Command and is responsible for defense of the homeland. VanHerck told The Associated Press that his command is rewriting the military’s current pandemic and infectious disease plans. Officials are also planning wargame exercises to test the abilities of U.S. military medical workers.
