During his tenure, Secretary of Defense Donald Rumsfeld raised the ire of the military by attempting to reform its structure away from traditional infantry and toward a lighter, faster, more technologically driven force. In April 2006, Rumsfeld was severely criticized by some retired military officers for his handling of the Iraq War, while other retired military officers came out in support of Rumsfeld. Although no active military officers have spoken out against Rumsfeld, the actions of these officers is still highly unusual. Some news accounts have attributed the actions of these generals to the Vietnam war experience, in which officers did not speak out against the administration's handling of military action. Later in the year, immediately after the November elections in which the Democrats gained control of the Congress, Rumsfeld resigned.
