What is a US Army Ruck?

As a soldier in the US Army, one of the essential pieces of equipment you will use is a ruck. But what exactly is a ruck? In simple terms, a ruck is a backpack designed specifically for military use. It’s a versatile and durable piece of equipment that can be used for various tasks, including carrying essential gear, supplies, and ammunition.

Definition of Ruck

A ruck is a military backpack designed to be used in various combat situations. It typically consists of a large main compartment, several smaller pockets and pouches, and a sturdy frame to provide support and distribute the weight evenly across the soldier’s back. Rucks come in different sizes and designs, but they all share the same purpose of providing soldiers with a reliable and comfortable way to carry their gear during missions.

The Difference Between Ruck and Backpack

While rucks and backpacks may look similar at first glance, they are quite different in terms of design and functionality. Backpacks are designed for everyday use, such as carrying books, electronics, or personal items. They typically have a soft frame and are not built to withstand the rigors of military use. Rucks, on the other hand, are specifically designed to withstand harsh conditions and heavy loads. They are built with a sturdy frame, durable materials, and multiple compartments to organize and carry essential gear.

Why is a Ruck Important in the US Army?

Rucks are an essential piece of equipment in the US Army because they allow soldiers to carry everything they need for a mission. From food and water to ammunition and medical supplies, a ruck can carry all the essential gear a soldier needs to complete their mission successfully. Without a ruck, soldiers would have to carry everything in their hands, making it challenging to move quickly and efficiently. Additionally, rucks help distribute the weight of the gear evenly across the soldier’s back, reducing the risk of injury and fatigue during extended missions.

Types of US Army Rucks

As an essential piece of equipment for every soldier, the US Army has developed several of rucksacks to meet different needs and situations. Here are the most common of US Army rucksacks:

Alice Pack

The Alice Pack, also known as the All-Purpose Lightweight Individual Carrying Equipment, has been the standard issue rucksack for the US Army since the 1970s. It is a frameless backpack made of nylon and has a capacity of around 50 liters. The Alice Pack features a large main compartment, three external pockets, and a padded shoulder strap. It is ideal for carrying light to medium loads and is very popular among hikers and outdoor enthusiasts.


The Modular Lightweight Load-carrying Equipment, or MOLLE Pack, is a modular backpack system used by the US Army. It is designed to be customizable and can be configured for different missions and personal preferences. The MOLLE Pack consists of a main rucksack and various modular pouches that can be attached to the exterior using a MOLLE webbing system. The MOLLE Pack has a capacity of around 70 liters and is ideal for carrying heavy loads.


The Improved Load Bearing Equipment, or ILBE Pack, is a newer generation rucksack used by the US Marine Corps. It is a large, frame-based backpack with a capacity of around 78 liters. The ILBE Pack is made of durable materials and features a comfortable padded waist belt and shoulder straps. It also has a detachable assault pack that can be used as a standalone backpack. The ILBE Pack is designed to carry heavy loads and is suitable for long-distance hikes and missions.


When considering which type of rucksack to use, it is important to understand the differences between the Alice Pack, MOLLE Pack, and ILBE Pack. The Alice Pack is a lightweight and simple backpack that is ideal for short hikes and carrying light to medium loads. The MOLLE Pack is a modular system that can be customized for different missions and preferences. It is ideal for carrying heavy loads and can be configured to suit individual needs. The ILBE Pack is a large and robust backpack that is designed for carrying heavy loads over long distances. It is suitable for long missions and hikes in tough terrain.

How to Properly Pack a US Army Ruck

When it comes to packing a US Army ruck, proper technique is essential. Not only does it ensure that all necessary items are included, but it also ensures that the weight is distributed evenly and comfortably across the wearer’s back. In this section, we’ll cover the importance of proper packing, provide a basic list, discuss ruck weight distribution, and highlight common packing mistakes to avoid.

Importance of Proper Packing

Proper is critical for any rucking mission, as it ensures that you have all the necessary gear and equipment to complete your mission safely and effectively. It also ensures that the weight is evenly distributed across your back, which can help prevent discomfort or injury. Additionally, proper can help you access gear quickly and efficiently, saving valuable time when seconds count.

Basic Packing List

If you’re new to rucking, or just need a refresher, here’s a basic list to get you started:

  • Clothing appropriate for the weather
  • Hydration system (water bladder or canteen)
  • First aid kit
  • Navigation tools (map, compass, GPS)
  • Food and snacks
  • Communication device (radio, phone)
  • Flashlight or headlamp with extra batteries
  • Gloves
  • Sun protection (hat, sunglasses, sunscreen)

Note: This is just a basic list, and depending on the mission, additional items may be required.

Ruck Weight Distribution

As previously mentioned, proper weight distribution is essential for a comfortable and safe rucking experience. The weight of the ruck should be evenly distributed between the shoulders and hips, with the majority of the weight resting on the hips. This is accomplished by adjusting the shoulder straps and hip belt accordingly.

In addition to the weight distribution, it’s also important to pack heavier items closer to the wearer’s back and higher up in the ruck. This helps maintain balance and stability, preventing the ruck from pulling away from the wearer’s back.

Common Packing Mistakes

Despite the importance of proper , there are some common mistakes that ruckers make. These mistakes can lead to discomfort, injury, or even mission failure. Here are some of the most common mistakes to avoid:

  • Overpacking: It’s easy to fall into the trap of thinking that more gear is better, but overpacking can lead to a heavier ruck and unnecessary items that take up valuable space.
  • Poor weight distribution: As previously mentioned, proper weight distribution is essential for a comfortable and safe rucking experience. Failing to distribute weight evenly can lead to discomfort or injury.
  • Improper packing order: Packing items in the wrong order can throw off the weight distribution and make it difficult to access necessary gear quickly.
  • Poor organization: Failing to organize gear can lead to valuable time wasted searching for necessary items. Separating gear into different compartments or using cubes can help keep things organized.

By avoiding these common packing mistakes and following proper techniques, you can ensure a safe and comfortable rucking experience.
