Answer: it's hard to know who has the best army or navy force but we can compare the number.
Step-by-step explanation:
In 2019, A new report from the U.S. Department of Defense claims the Chinese Navy, known officially as the People's Liberation Army Navy (PLAN), is the largest in the world. According to the Pentagon, the PLAN has 350 battle force ships, as opposed to the U.S. Navy's 293 ships
According to statista, in 2020, The United States in comparison, has significantly less - 1.4 million - but when assessing the overall power of the world's military forces, the U.S. comes out on top, ahead of Russia and China in second and third, respectively.
