## Core Evaluations and Physical Assessments During the initial days under the supervision of the 4th RTB, candidates must pass several gate events to remain in the course. These assessments include: * **Ranger Physical Assessment (RPA):** Candidates must complete a specific number of push-ups, sit-ups, and chin-ups, followed by a timed five-mile run. Strict form is enforced, and failing to meet the minimum repetitions or time limits results in dismissal. * **Combat Water Survival Assessment (CWSA):** This test evaluates a candidate's ability to survive in water while wearing full combat gear. It includes a log walk, a rope drop, and an underwater equipment discard. * **Land Navigation:** Candidates must successfully navigate difficult, wooded terrain during both day and night conditions, locating a set number of points within a designated timeframe without the aid of electronic devices. * **The Darby Queen:** A challenging obstacle course consisting of over twenty demanding obstacles designed to test upper body strength, balance, agility, and mental stamina. ## Tactical Training and Squad Operations
Once candidates pass the physical gates of RAP week, the 4th RTB shifts its focus to tactical instruction. Under the guidance of Ranger Instructors (RIs), candidates learn and execute squad-level operations. This training emphasizes: * **Troop Leading Procedures (TLPs):** Candidates are evaluated on their ability to plan, prepare, and execute combat missions under pressure. * **Patrolling and Reconnaissance:** Instruction covers squad patrols, ambushes, and reconnaissance missions, forcing candidates to apply tactical theory in field environments. * **Peer Evaluations:** Candidates rate their peers on leadership ability, teamwork, and reliability. These evaluations are critical, as poor peer ratings can result in dismissal from the course. ## The Role of Ranger Instructors The backbone of the 4th Ranger Training Battalion is its cadre of Ranger Instructors. These experienced non-commissioned officers and officers are responsible for mentoring, evaluating, and safety-monitoring the candidates. RIs apply constant pressure to simulate the stress of actual combat operations. They assess candidates not just on tactical success, but on their ability to lead and make decisions under extreme physical fatigue and mental stress.
## Historical Legacy of the Darby Phase The phase conducted by the 4th RTB is named in honor of Brigadier General William O. Darby, who organized and led the first U.S. Army Ranger Battalions during World War II. The training philosophy of the 4th RTB reflects this heritage, focusing on the core principles of elite light infantry tactics, adaptability, and resilient leadership. ## Preparing for the Next Phase The ultimate objective of the 4th Ranger Training Battalion is to prepare successful candidates for the rigors of the Mountain Phase (conducted by the 5th Ranger Training Battalion in Dahlonega, Georgia) and the Swamp Phase (conducted by the 6th Ranger Training Battalion at Eglin Air Force Base, Florida). By enforcing strict standards and demanding tactical proficiency, the 4th RTB ensures that only those with the necessary physical stamina, leadership potential, and tactical competence advance in the quest to earn the Ranger Tab.
