The US Army maintains a long-standing tradition dating as far back as 1775 when the first companies of "riflemen" were formed by the Continental Congress. The branch went on to see notable and extensive combat actions through many of America's commitments including the Revolutionary War (1785-1783), the War of 1812, the American Civil War (1861-1865), World War 1 (1914-1918), World War 2 (1939-1945), the Korean War (1950-1953), the Vietnam War (1955-1975), Grenada (1983), Panama (1989-1990) and the Persiab Gulf War (1991).
More recently, U.S. Army personnel have been involved as part of the War in Afghanistan (2001) and the Invasion of Iraq (2003). The branch is regarded as one of the most powerful in the world based on combat experience, equipment quality and training alone.
NOTE: The Five Star rank is generally reserved for wartime only and can also be used as an honorary rank.
