The US consists of a rich mosaic of different races, religions and cultures. In the 224 years since our founding, we have come a long way, in terms of race relations. Despite a history of both de jure and de facto segregation, up through the early 1960s, America has made significant progress when it comes to inclusion. The US Army has the proud distinction of being the lead agent when it comes to changes in social patterns and mores. When President Harry S Truman signed Executive Order 9981, integration of the Armed Forces became the order of the day. In the intervening 52 years the Army has become the standard setter for race relations. In recent years, since the mid-1990s, there has been an alarming increase in difficulties. These include increased official reports of discrimination, falling selection and promotion rates for African- American officers, and anecdotal evidence that junior grade Black officers are not being mentored and developed by their chain of command. 收起
