a detailed justification for such proposed obligations. 203. Plan to maintain a forward-stationed combat aviation brigade in South Korea (a) Findings Congress finds the following: (1) The National Commission on the Future of the Army established by the National Commission on the Future of the Army Act of 2014 (title XVII of Public Law 113–291 ) found that the Army is incurring unacceptable risk in capabilities that would be required early for major contingencies, and that retaining an eleventh combat aviation brigade in the regular Army would help meet these demands. (2) The Commission also found that with an eleventh combat aviation brigade, the Army would be better postured to retain a forward stationed aviation brigade in South Korea, a major advantage over rotating forces as currently planned, and shortfalls in capabilities would decline significantly.
