the sequence was changed to Fort Benning, Desert (Fort Bliss, Texas), Mountain, and Florida. In May 1995, the school underwent its most recent course change when the Desert phase was discontinued. The last Ranger School class to go through the Desert Phase was class 7–95. The U.S. Army has not given up on small unit desert training. In 2015, the 1st Armored Division created the Desert Warrior Course that focuses on honing combat tracking, night land navigation, live-fire drills, and a myriad of other tasks. Leadership positions A student's graduation is highly dependent on their performance in graded positions of leadership. This leadership ability is evaluated at various levels in various situations, and is observed while they are in one of typically two graded leadership roles per phase. The student can either meet the high standards and be given a "GO" by the R.I., or can fail to meet this standard and receive a "NO GO". The student must demonstrate the ability to meet the standard in order to move forward, and can thus only afford one unsuccessful patrol. The student's success will lie in his ability to essentially manipulate those directly underneath their charge of leadership. At times, this will be as few as two to three people—and at other times the student may be required to lead up to an entire 45-person platoon. The student's success can be dependent on the performance and teamwork of these individuals, whom they must motivate and lead. Missions are typically broken up into four stages: planning, movement, actions on the objective, and establishment of a patrol base. The Platoon Leader position (in Mountains and Florida) will be rotated throughout the mission, and the same is true for the platoon sergeant position. The squad leader position is on a 24-hour rotation which is the same for all of the ungraded key leadership positions: Medic, Forward Observer (FO) and Radio Telephone Operator (RTO). Peer evaluations Another part of the evaluation of the student is a peer evaluation; failing a peer evaluation (scoring less than a 60% approval rating from your squad) can result in disqualification, though usually only if it happens twice. Due to unit loyalties, certain individuals within a squad who may be "the odd one out" will sometimes be singled out by the squad arbitrarily. Because of this, someone who has been "peered out" or "peered," will be moved to another squad,
