The United States accounts for more than one-third of military spending worldwide and spends 3.5% of its GDP or a whopping $585 billion every year on its armed forces. That being said, it is considered to be the world's most advanced and technologically capable, and every year is involved in operations across the planet; helping disaster-struck countries in aid efforts, helping new regimes stabilize, and engaging in numerous covert operations.

The US Navy, in particular, is the largest and most capable one in the world and has over 300,000 personnel on active duty at any given time. 2017 has been a very busy year for them, with Hurricane Harvey, Irma, and Maria meaning that rescue efforts were required in many of the country's states and territories. As the year winds down, the Armed Forces have released their most powerful images and we've collected the 30 of their best:
