SFAS vs RASP: Which Army Selection Is Right for You?
Quick answer: RASP (Ranger Assessment and Selection Program) is an eight week selection at Fort Moore, Georgia that fills the 75th Ranger Regiment, the Army's premier direct action raid force. SFAS (Special Forces Assessment and Selection) is a roughly 24 day assessment at Camp Mackall, North Carolina that picks candidates for the Special Forces Qualification Course and a Green Beret career. Choose RASP if you want high tempo direct action soon; choose SFAS if you want unconventional warfare and a longer, more autonomous career arc.
What Is RASP?
RASP stands for Ranger Assessment and Selection Program. If you searched "define RASP," that is the answer: it is the 75th Ranger Regiment's in-house tryout, run at Fort Moore, Georgia (formerly Fort Benning). It is not Ranger School, and that distinction matters. More on it below.
RASP comes in two versions. RASP 1 is the roughly eight week course for junior enlisted soldiers and junior NCOs in pay grades E-1 through E-5. RASP 2 is a shorter course, about three weeks, for senior NCOs, warrant officers, and officers volunteering for the Regiment. Both end the same way: assignment to the 75th Ranger Regiment if you meet the standard.
To start RASP 1 you must pass Ranger screening (psychological review, background check, urinalysis) plus an entry fitness assessment that has historically included 53 push-ups, 63 sit-ups, a 2 mile run in 14:30 or faster, at least 4 pull-ups, and a 6 mile ruck march with a 35 pound load in under 90 minutes. From there, the course assesses physical endurance, ruck marching, land navigation, marksmanship, breaching, medical skills, and your ability to keep performing under constant cadre pressure and limited sleep. Historical attrition for RASP 1 has run near 47 percent, and some classes lose more than half. Before you ship, project your readiness with our RASP calculator.
What Is SFAS?
SFAS is Special Forces Assessment and Selection, an approximately 24 day assessment held at Camp Mackall, North Carolina. It is the gate into the Special Forces Qualification Course (SFQC) and, eventually, a Green Beret ODA. Candidates must be U.S. Army soldiers who are airborne qualified or volunteer for airborne training, meet fitness prerequisites, and pass a swim assessment.
The course itself is famously quiet. Cadre observe more than they yell. You will face day and night land navigation, timed rucks, team events with logs and loaded litters, and the Star Course, a long range individual movement event covering 40 plus miles of self-paced land navigation. SFAS measures problem solving, grit, and how you behave when nobody is motivating you. Selection rates have historically ranged from roughly a third of candidates to the mid 40 percent range depending on the class, which puts attrition well above half in many years.
Getting selected is only the start. The SFQC that follows runs roughly one to two years (about 56 to 95 weeks) depending on your MOS and assigned language. Gauge where you stand today with our SFAS calculator.
SFAS vs RASP: Side by Side
| Category | SFAS | RASP |
|---|---|---|
| Length | About 24 days | About 8 weeks (RASP 1); about 3 weeks (RASP 2) |
| Location | Camp Mackall, NC | Fort Moore, GA |
| Who attends | Soldiers and 18X candidates seeking Special Forces | E-1 to E-5 (RASP 1); senior NCOs, warrants, officers (RASP 2) |
| Selects for | Entry to the SFQC and a Green Beret career | Assignment to the 75th Ranger Regiment |
| Fitness emphasis | Heavy rucking, land navigation, the Star Course | Entry PT test, constant smoke sessions, rucks, and standards under fatigue |
| What comes after | SFQC, roughly 1 to 2 years | Ranger battalion, then Ranger School as a leader |
| Historical attrition | Often 55 to 70 percent not selected | Near 47 percent for RASP 1, sometimes higher |
Both communities now test under the Army Fitness Test (AFT), which replaced the ACFT on June 1, 2025. The AFT has five events: the 3 repetition maximum deadlift, hand release push-ups, the sprint drag carry, the plank, and a 2 mile run. Soldiers in the 21 designated combat specialties, which include Special Forces 18 series and Ranger Regiment infantry slots, must hit the sex neutral combat standard of 350 points with at least 60 points per event. Treat 350 as a floor, not a goal. Competitive candidates at either selection score far above it.
Ranger School vs RASP: Not the Same Thing
This trips up a lot of future soldiers, so let's be precise. RASP is a selection program: it decides whether you get to serve in the 75th Ranger Regiment. Ranger School is a roughly two month Army leadership school, open to soldiers across the force, that teaches small unit combat leadership and awards the Ranger tab. You can earn the tab and never serve in Regiment, and new Rangers serve in Regiment before they ever attend Ranger School, which most attend later as part of their development.
Ranger School also updated its entry test. The RPFA 2.0, effective April 21, 2025, is a two phase day one assessment: a seven event combat readiness circuit completed in 14 minutes or less, followed by a 4 mile run in 32 minutes and 6 chin-ups. Full details are in our guide to Ranger School requirements, the RPFA, and phases.
Which Path Fits Which Soldier
Lean toward RASP and the Regiment if:
- You want direct action: raids, airfield seizures, high tempo rotations
- You thrive on structure, discipline, and cadre-driven intensity
- You want to reach an elite unit early in your career, including straight from initial entry with a Ranger contract
Lean toward SFAS and Special Forces if:
- You want unconventional warfare, foreign internal defense, and work with partner forces
- You perform best with autonomy and solve problems without supervision
- You can commit to a pipeline that takes one to two years after selection, including language training
Neither path is a shortcut to the other, and neither is "easier." They select for different soldiers doing different work.
How to Train for Either
The overlap is bigger than the differences. Build an aerobic base with running and rucking, get strong enough to move loads repeatedly, and harden your feet months before you show up. For SFAS, prioritize heavy rucks and land navigation under fatigue. For RASP, prioritize running volume, calisthenics density, and recovery between repeated daily events. For both, train the AFT events until the combat standard feels routine, and benchmark yourself regularly with our full suite of military PT calculators.

What does RASP stand for?
RASP stands for Ranger Assessment and Selection Program. It is the selection course every soldier must pass to serve in the 75th Ranger Regiment. RASP 1 serves junior enlisted soldiers, and RASP 2 serves senior NCOs and officers.
Is RASP harder than SFAS?
They are hard in different ways. RASP is longer at eight weeks and applies constant cadre pressure, physical smoke sessions, and daily performance standards. SFAS compresses heavier ruck loads, land navigation, and the 40 plus mile Star Course into about 24 days with minimal feedback. By the numbers, SFAS non-selection rates have often been higher, but the honest answer is that each course is hardest for the soldier unsuited to it.
Is RASP the same as Ranger School?
No. RASP is the selection for the 75th Ranger Regiment. Ranger School is a leadership school that awards the Ranger tab and is open to qualified soldiers across the Army. Regiment Rangers pass RASP first and typically attend Ranger School later.
How long is RASP?
RASP 1 lasts about eight weeks at Fort Moore, Georgia. RASP 2, the version for senior NCOs, warrant officers, and officers, runs about three weeks.
Can you go from the Rangers to Special Forces?
Yes, and many do. Time in Regiment builds the fitness base and field craft that serve SFAS candidates well. The reverse also happens, though less often. Neither selection requires the other.
