Rangers Lead the Way

RAP Week is the single biggest filter in Ranger School. More students are dropped during these 4 days than in all other phases combined. If you pass RAP, you have roughly a 75–80% chance of graduating.

All events are pass/fail with no retests. The Ranger Physical Assessment (RPAT), 5-mile run, and land navigation are the top three eliminators. You must also complete the combat water survival assessment, 12-mile ruck march, and demonstrate proficiency on Ranger stakes — task-specific evaluations covering demolitions, call for fire, and medical procedures.

Key stat: The physical assessment is the #1 cause of RAP failure. Land navigation is #2. Train both aggressively before you arrive.

Darby Phase is the first graded patrol phase, focused on small unit tactics in the wooded terrain around Fort Moore. Students plan and execute squad-level ambushes, reconnaissance, and raid operations while rotating through graded leadership positions.

This is where Ranger School gets real — severe sleep and food deprivation begin. Students operate on ~2–3 hours of sleep per night and 1–2 MREs per day while burning 5,000+ calories. You must demonstrate the ability to lead a patrol to standard under these conditions.

Students who don't earn at least one GO in a graded leadership position will be recycled (start Darby over) or dropped from the course. Peer evaluations also factor in — bottom performers get a "lack of motivation" (LOM) drop.

Mountain Phase takes place at Camp Frank D. Merrill in the north Georgia mountains near Dahlonega. Students learn military mountaineering skills and execute platoon-level combat patrols in steep, heavily wooded terrain with significant elevation changes.

The physical demands escalate dramatically — students carry 80+ lb rucks up and down mountains while continuing to operate on minimal sleep and food. The terrain is unforgiving: movements take 2–3x longer than flat ground, and injuries spike.

Students must earn at least one GO in a graded platoon leadership position (PL, PSG, SL) and pass the knots/rappelling evaluation. The Tennessee Valley Divide FTX is the culminating multi-day field exercise.

Swamp Phase is the final phase of Ranger School, conducted at Camp James E. Rudder on Eglin Air Force Base in the Florida panhandle. Students execute platoon-level operations in coastal swamp, jungle, and waterway terrain.

This phase introduces waterborne operations using Zodiac rubber boats, stream and swamp crossings, and patrols through waist-deep water. Students are physically broken down after 40+ days of sleep and food deprivation but must continue to plan and lead combat patrols to standard.

Swamp Phase is also the last chance to earn GOs. Students need an overall GO rate of at least 50% across all phases to graduate. Those who don't meet the standard may be recycled to the beginning of Florida Phase or dropped entirely.

Cold weather demands cold weather gear. Mountain phase in the winter will test your limits — waffle layers, beanies, and glove inserts aren't optional. Frostbite, hypothermia, and frozen equipment are real threats.

Your ruck will freeze overnight. Water sources freeze. Your hands stop working. Sleep deprivation hits harder when your body is burning calories just to stay warm. Winter Rangers earn their tab in some of the harshest conditions the course offers.

Florida phase in the spring means relentless bugs and wet conditions. 100% DEET, permethrin-treated gear, and waterproof everything keeps you in the fight. Bug bites get infected fast when you're sleep-deprived and living in standing water.

Spring classes deal with wildly variable weather — cold mornings in the mountains, hot humid afternoons in Florida. You need gear that handles both extremes. Rain is constant and everything stays wet.

Summer is the most physically punishing season. Heat casualties are the biggest threat — the combination of 100°F+ temperatures, full combat load, sleep deprivation, and caloric deficit creates dangerous conditions every single day.

Hydration is everything. You'll drink more water than you thought possible and still feel dehydrated. The Florida swamp phase in summer heat is brutal — standing in chest-deep warm water with no breeze while wearing full kit.

Fall is widely considered the "best" season for Ranger School — if such a thing exists. Temperatures are moderate, bugs are tapering off, and you avoid the extremes of summer heat and winter cold. But don't get complacent.

The mountains in October and November can get cold fast, especially at elevation. Temperature swings are the main challenge — warm during the day, near-freezing at night. You still need cold weather layers for mountains and light layers for Florida.
