After nearly two years of bitter skirmishes between the three components of the U.S. Army — Active, National Guard, and Reserve — a congressionally mandated commission of retired Army leaders and Department of Defense officials will study the current force structure of America’s land force and make recommendations on its future composition. Though the National Commission on the Future of the Army was formed as a result of sparring between the three Army components and their interest groups, it presents an opportunity to create an Army capable of meeting the complex security threats our nation faces today and into the 21st century. With the Islamic State still controlling large swaths of Iraq and Syria, renewed uncertainty in Afghanistan and Russia’s perpetuation of “frozen conflicts” along its western border, the need for a decisive land force capable of meeting conventional, asymmetric and hybrid threats is as critical as ever. So how can the Regular Army, Army National Guard, and Army Reserve work better to achieving that end? Here are four recommendations for the National Commission on the Future of the Army to consider.
