What Is RASP and How the Ranger Assessment and Selection Program Works

The term "Rasp Army" is a common phonetic misunderstanding often encountered by those unfamiliar with United States military terminology. There is no independent military branch or specific organization officially titled the Rasp Army. Instead, the term refers to RASP, the Ranger Assessment and Selection Program. This is the grueling, elite selection process that serves as the exclusive gateway for soldiers wishing to join the 75th Ranger Regiment, the U.S. Army’s premier large-scale special operations raiding force.

To understand RASP is to understand the difference between being a soldier and being a Ranger. While many soldiers in the Army may earn a Ranger Tab by attending the leadership-focused Ranger School, only those who successfully navigate the RASP pipeline earn the tan beret and the right to serve within the 75th Ranger Regiment. This distinction is critical for anyone looking to understand the structure of American special operations.

Defining the Ranger Assessment and Selection Program

RASP is a specialized selection and training pipeline designed to identify soldiers who possess the physical toughness, mental fortitude, and moral character required to operate in high-stress, high-stakes combat environments. It is conducted at Fort Moore, Georgia (formerly Fort Benning), and is managed by the Regimental Selection Training Detachment of the 75th Ranger Regiment.

The program serves two primary functions. First, it acts as a filter to remove candidates who do not meet the Regiment's uncompromising standards. Second, it serves as an indoctrination period, teaching candidates the specific tactics, techniques, and procedures (TTPs) used by the Regiment, as well as its unique culture and history.

The selection is divided into two distinct versions based on the candidate's rank and experience: RASP 1 and RASP 2.

The Evolution from RIP and ROP to RASP

The current iteration of the program was established in January 2010. Prior to this, the selection process was known as the Ranger Indoctrination Program (RIP) for enlisted soldiers and the Ranger Orientation Program (ROP) for officers. RIP was typically a four-week course that focused heavily on physical attrition.

However, as the Global War on Terror progressed, the 75th Ranger Regiment realized that a longer, more skill-intensive program was necessary. The transition to RASP extended the duration to eight weeks for junior enlisted soldiers, allowing for a better balance between physical assessment and technical skill development. This ensures that when a new Ranger arrives at their battalion, they are not just physically fit but are also proficient in basic marksmanship, medical skills, and small-unit tactics specific to the Regiment's mission set.

RASP 1 The Journey for Junior Enlisted Soldiers

RASP 1 is an eight-week program designed for soldiers in the pay grades of E-1 through E-5. This category includes the majority of new recruits who have just completed Basic Combat Training (BCT) and Advanced Individual Training (AIT), as well as junior noncommissioned officers transferring from other Army units.

The eight-week course is split into two four-week phases.

Phase 1 Assessment and Mental Toughness

The first four weeks of RASP 1 are notoriously difficult and are designed to test a candidate's limit. This phase focuses on the "Big Five" of Ranger excellence: physical fitness, marksmanship, medical proficiency, small-unit tactics, and discipline.

Candidates are subjected to "Smoke Sessions," which are intense periods of corrective physical training intended to induce fatigue and stress. The goal is not just to see who is strong, but to see who maintains their discipline and focus when they are exhausted, cold, hungry, and sleep-deprived.

A pivotal part of Phase 1 is the time spent at Cole Range. This is a remote training area where candidates undergo several days of continuous operations. Sleep is minimal—often totaling only a few hours over multiple days—and the physical demands are constant. Candidates perform repeated "wood line" runs, land navigation exercises, and long-distance movements under load. It is common for a significant percentage of the class to "Drop on Request" (DOR) during the first week of Phase 1 or during the Cole Range portion.

Key requirements in Phase 1 include:

• The Ranger Physical Fitness Test (RPFT): Consisting of push-ups, sit-ups, a five-mile run, and pull-ups, all scored to a strict standard.
• 12-Mile Ruck March: Candidates must complete a 12-mile march carrying a minimum of a 35-pound dry rucksack (plus water and gear) in under three hours.
• Water Survival: A 15-meter swim in full uniform and gear to ensure candidates can operate in aquatic environments.
• Land Navigation: Demonstrating the ability to find specific points in dense woods during both day and night using only a map and compass.

Phase 2 Skills and Lethality

Candidates who survive the first four weeks move into Phase 2. While the physical intensity remains high, the focus shifts toward the technical skills required of a 75th Ranger Regiment member.

During this phase, candidates receive advanced instruction in:

• Marksmanship: Moving beyond basic Army standards to master the optics and weapon systems used by the Regiment. Candidates spend significant time on the range practicing "close quarters battle" (CQB) techniques and stress shoots.
• Breaching: Learning the fundamentals of how to enter buildings and fortified positions using mechanical, ballistic, and explosive methods.
• Special Operations Combat Medic (SOCM) Skills: Every Ranger is expected to have a higher level of medical proficiency than a standard soldier. Phase 2 introduces them to the Tactical Combat Casualty Care (TCCC) protocols that save lives on the battlefield.
• Airfield Seizure and Raiding: The primary missions of the Regiment. Candidates learn how to conduct fast-paced raids, secure objectives, and handle detainees.

RASP 2 The Selection for Leaders

RASP 2 is a three-week program for senior noncommissioned officers (E-6 and above), officers, and warrant officers. Because these candidates are expected to lead Rangers, the selection criteria are different. They are assumed to already possess a high level of physical fitness and basic tactical knowledge.

RASP 2 focuses on leadership under pressure. Candidates are evaluated on their ability to make sound decisions in complex, ambiguous environments. They are also briefed on the Regimental standards for administrative, logistical, and operational management. For an officer or senior NCO, failing RASP 2 often means they will not have the opportunity to serve in the 75th Ranger Regiment for the remainder of their career.

Entry Requirements and Standards

Joining the 75th Ranger Regiment is not open to everyone in the Army. There are specific prerequisites that a soldier must meet before they are even allowed to step onto the RASP grounds.

General Prerequisites

• U.S. Citizenship: Required for the security clearances necessary for special operations.
• Active Duty Status: Only active-duty soldiers are eligible; the Regiment does not currently recruit from the National Guard or Reserves.
• Security Clearance: All candidates must be eligible for a Secret security clearance.
• ASVAB Scores: Candidates must have a General Technical (GT) score of 105 or higher on the Armed Services Vocational Aptitude Battery.

Physical Standards

The physical requirements are the most visible barrier to entry. While the Army Combat Fitness Test (ACFT) is the current baseline for the regular Army, RASP continues to use the Ranger Physical Fitness Test (RPFT) and other specific metrics to ensure candidates meet the Regiment's higher standards:

• Push-ups: Minimum of 58 (traditional) or 41 (hand-release) in two minutes, with perfect form.
• Sit-ups: Minimum of 69 in two minutes.
• 5-Mile Run: Must be completed in 40 minutes or less.
• Pull-ups: Minimum of 6 (dead hang, no kipping).
• 12-Mile Ruck: 35-pound dry load in under 3 hours.

RASP vs Ranger School Clearing the Confusion

One of the most frequent points of confusion for both civilians and soldiers is the difference between RASP and Ranger School. While they share the name "Ranger," they serve entirely different purposes.

What is Ranger School?

Ranger School is a 61-day leadership and small-unit tactics course. It is open to soldiers from across the entire Army, as well as members of other military branches and even foreign allies. The primary focus of Ranger School is teaching soldiers how to lead teams under extreme stress, hunger, and sleep deprivation in three different environments: woodlands, mountains, and swamps.

Graduates of Ranger School earn the Ranger Tab, which is a permanent decoration worn on the left shoulder of the uniform. However, earning a Ranger Tab does not make you a member of the 75th Ranger Regiment. Most people who have a Ranger Tab serve in regular infantry, airborne, or armored units.

What is RASP?

As established, RASP is the selection program for the 75th Ranger Regiment. You cannot join the Regiment without passing RASP. When a soldier passes RASP, they are awarded the Ranger Scroll (the unit patch of the 75th Ranger Regiment) and the Tan Beret.

In the special operations community, a "Scroll-bearing Ranger" is someone who is currently assigned to the 75th Ranger Regiment. While many Rangers in the Regiment will eventually go to Ranger School to earn their Tab (which is often a requirement for promotion to leadership positions within the Regiment), it is RASP that grants them entry into the unit.

Key Comparison Table:

The Psychological Element of RASP

The physical attrition of RASP is significant, but the mental game is where most candidates fail. The program is designed to create an "environment of the unknown." Candidates are rarely told how long a specific task will last or what the next event will be. This constant uncertainty is intended to identify soldiers who can maintain their composure when their plans fall apart.

Peer Evaluations

One of the most critical components of the selection process is the peer evaluation system. Multiple times throughout the course, candidates are asked to rank their peers. They must identify who they would most want to go into combat with and who they would least want by their side.

If a candidate is physically elite but is viewed by their peers as selfish, lazy, or dishonest, they will be dropped from the program. The 75th Ranger Regiment prioritizes the team over the individual. A "superstar" who cannot work within the team dynamic is of no use to the Regiment.

The Cadre Influence

The instructors, or Cadre, are all seasoned Rangers from within the Regiment. They are not there to "train" candidates in the traditional sense during Phase 1; they are there to evaluate them. Every interaction, from the way a candidate stands at attention to how they carry their rucksack, is scrutinized. The Cadre look for "trainability"—the ability of a soldier to receive a correction and immediately implement it without ego.

The Role of the 75th Ranger Regiment

To understand why RASP is so difficult, one must look at what is expected of the 75th Ranger Regiment. Unlike some special forces units that focus on unconventional warfare or training foreign militaries, the Rangers are a direct-action force. They are the "scalpel" of the U.S. Army, used for high-risk missions including:

• Airfield Seizures: Taking and holding enemy airfields to allow for the follow-on flow of forces.
• Special Operations Raids: Capturing or eliminating high-value targets (HVTs).
• Personnel Recovery: Rescuing captured or isolated personnel in hostile territory.
• Special Reconnaissance: Gathering intelligence deep behind enemy lines.

Because these missions often involve fast-roping from helicopters or parachuting into enemy territory under the cover of darkness, there is zero room for error. A single soldier who panics or fails to meet the physical standard can jeopardize the entire mission and the lives of their teammates.

Gender Integration in RASP

For most of its history, the 75th Ranger Regiment was a male-only unit. However, following the Department of Defense's 2013 decision to open all combat roles to women, the selection process was integrated. In 2017, the first woman successfully passed RASP 2 and earned her position within the Regiment.

The standards for RASP were not lowered for female candidates. The 75th Ranger Regiment maintained that mission effectiveness depends on the standard, not the person. Female candidates must pass the same RPFT, the same 12-mile ruck march, and the same peer evaluations as their male counterparts. This gender-neutral approach ensures that every person wearing the tan beret has earned it through the same crucible.

Life After RASP: The Ranger Creed

Graduating from RASP is only the beginning. New Rangers are assigned to one of the Regiment's five battalions:

• 1st Battalion, 75th Ranger Regiment (Hunter Army Airfield, GA)
• 2nd Battalion, 75th Ranger Regiment (Joint Base Lewis-McChord, WA)
• 3rd Battalion, 75th Ranger Regiment (Fort Moore, GA)
• Regimental Special Troops Battalion (RSTB)
• Regimental Military Intelligence Battalion (RMIB)

Upon arrival, they are expected to live by the Ranger Creed. This six-stanza document outlines the philosophy of the Regiment. It emphasizes that a Ranger is "a more elite soldier," that they will "never leave a fallen comrade to fall into the hands of the enemy," and that they will always "shoulder more than their share of the task, whatever it may be, one-hundred percent and then some."

Life in the Regiment involves a high operational tempo. Even when not deployed, Rangers are constantly training. This includes advanced schools like Airborne School, Pathfinder, Jumpmaster, and eventually, the grueling 61-day Ranger School to earn their Tab.

Conclusion and Summary

The term "Rasp Army" is a misnomer for the Ranger Assessment and Selection Program (RASP), the essential gateway to the U.S. Army's elite 75th Ranger Regiment. RASP is not a separate army but a world-class selection process that transforms high-performing soldiers into specialized special operations assets.

Through two phases of intense physical assessment and technical skill building, RASP ensures that only those with the highest levels of discipline and lethality earn the right to wear the tan beret. While often confused with Ranger School, RASP is the specific requirement for unit membership, whereas Ranger School is a leadership course.

Whether you are a civilian trying to understand military terminology or a prospective recruit preparing for the challenge, RASP stands as a testament to the Army's commitment to maintaining a force that is always ready to "Lead the Way."

Frequently Asked Questions

What is the failure rate of RASP?

While the Army does not release official day-to-day statistics, the attrition rate for RASP 1 is widely reported to be between 50% and 70%. Most candidates who fail do so in the first week or during the Cole Range portion of Phase 1.

Can you try again if you fail RASP?

It depends on why the candidate failed. Those who "Drop on Request" (quit) are rarely allowed back. However, those who are dropped for medical reasons or who fail a specific technical standard (like land navigation) may be allowed to return in a later class, provided their home unit supports the second attempt.

Do I have to go to Airborne School before RASP?

Historically, most candidates attended Airborne School before RIP/RASP. Under the current RASP 1 pipeline, candidates often attend Basic Training and AIT, then move directly into RASP. If they graduate, they then attend Airborne School before being assigned to their Ranger Battalion.

What is the most difficult part of RASP?

Most graduates cite the psychological stress of Cole Range and the 12-mile ruck march as the most difficult hurdles. The combination of sleep deprivation and the constant requirement to perform at a high physical level is what breaks most candidates.

Is the 75th Ranger Regiment part of Special Forces?

In the strict sense of U.S. Army terminology, "Special Forces" refers specifically to the Green Berets. However, the 75th Ranger Regiment is a key component of the U.S. Army Special Operations Command (USASOC) and is considered a Special Operations Force (SOF).
