Design Analysis of New-Generation Combat Load-Carrying Systems: Modularity and Integrated Protection-Carriage Technology in Tactical Vests, Assault Packs, and Sustainment Rucksacks

1. Introduction: Evolution from "Single-Purpose Carriage" to "Integrated Protection-Carriage"

The development of individual load-carrying equipment has undergone a long evolutionary process. From the "miscellaneous" gear of the revolutionary war period to the "left for sustainment, right for combat" configuration in the early years of the People's Republic, to later "modular custom combinations," and now to "integrated protection-carriage"-the individual combat load-carrying systems of the armed forces have changed dramatically.

The old-style rucksacks that served only a single storage function can no longer meet modern operational requirements. New-generation combat load-carrying systems are no longer merely "bags for carrying things"-they have become integrated individual soldier platforms combining protection, load carriage, and information integration.

On September 3, 2025, during the military parade commemorating the 80th anniversary of the victory of the Chinese People's War of Resistance against Japanese Aggression and the World Anti-Fascist War, a new-generation combat load-carrying system was officially unveiled, comprising multiple components, including a tactical vest, assault pack, and sustainment rucksack. This system features robust load-carrying and attachment capabilities, with characteristics such as easy donning/doffing, integrated protection-carriage, and information integration, while also offering good comfort, flexibility, and flame resistance.

This article starts with the three major components-tactical vest, assault pack, and sustainment rucksack-to systematically analyse the design logic and technical parameters of modern combat load-carrying systems.

2. The MOLLE/PALS System: The Technical Foundation of Modularity

Before delving into each component, it is necessary to understand the underlying technology that supports the entire modular system-the MOLLE system.

MOLLE (Modular Lightweight Load-carrying Equipment) is the world's most prevalent modular load-carriage standard for military and tactical gear. Its technical core is the PALS (Pouch Attachment Ladder System) - a grid of standardised 1-inch-wide webbing with 1-inch spacing, through which pouches are attached via interlocking straps, achieving a high degree of modularity and interoperability.

Through the MOLLE system, soldiers can flexibly combine modular components-tactical vests, assault packs, and various pouches-according to mission requirements, achieving personalised configurations. The core value of modularity lies in two aspects: standardisation-equipment that conforms to the standard can be combined interchangeably; and customization-operators can independently decide the quantity and placement of carried gear based on mission needs, tactical role, and personal preference.

Modular design is at the heart of the tactical vest. Based on the MOLLE system, it allows soldiers to freely assemble configurations as if "building with building blocks." In the latest combat load-carrying system, this philosophy is carried through to every component-not only does the tactical vest require "modular loading," but soldiers of different branches and specialities can also "build with building blocks," integrating into operations and training across various mission contexts.

3. Tactical Vest: The "All-Purpose Platform" for Modular Carriage and Ballistic Protection

The tactical vest is the core component of the new-generation combat load-carrying system and the most concentrated embodiment of the "integrated protection-carriage" concept.

3.1 The Integrated Protection-Carriage Design Philosophy

"Integrated protection-carriage" refers to the integration of equipment carriage function and ballistic protection function into a single piece of gear. In the traditional model, soldiers had to wear both a ballistic vest and a tactical vest (or chest rig) - two layers that not only added weight and bulk but also restricted mobility. The new-generation tactical vest combines both into one-the vest itself is capable of carrying ballistic plates, while its surface is covered with MOLLE webbing for attaching various pouches.

This advanced tactical vest features a lightweight modular design and a unique three-layer load-distribution system that accommodates both soft and hard armour options to customise ballistic protection according to specific missions.

3.2 Modular Protection Configuration

The greatest advantage of modular design is on-demand arming and flexible combination. The new tactical vest offers a complete suite of protective modules, including:

Users can freely choose combinations based on mission type and protection level. For high-intensity assault missions, the full suite of protection modules can be attached; for light patrols, only the vest body is retained, achieving "weight reduction with increased effectiveness."

3.3 Lightweighting and Laser-Cut Technology

Modern tactical vests pursue extreme lightweighting in materials and processes. The vest body uses laser-cut lightweight construction, maximising weight reduction while maintaining strength. Some advanced vests (without ballistic plates) can weigh as little as 1.1 kg.

Laser-cut technology also enables more precise and lighter MOLLE webbing attachment, eliminating the extra weight and bulk of traditional sewn-on webbing.

3.4 Easy Donning/Doffing and Quick-Release Design

The new tactical vest features significant improvements in donning and doffing convenience. Quick-release designs allow the vest to be shed rapidly in emergency situations. Some products also incorporate a quick-pull webbing system-a single pull is all it takes for rapid release.

4. Assault Pack: The "Mobile Resupply Point" for Rapid Access

The assault pack is the tactical mission component of the new combat load-carrying system, used to carry ammunition, communications equipment, medical supplies, and other items frequently accessed during combat.

4.1 Modular Compartments and Rapid-Access Design

The new assault pack features a "main compartment + front compartment" modular design, refined through hundreds of operational tests. Its design core is rapid access-in the heat of combat, soldiers have no time to rummage through packs.

The front compartment uses a magnetic quick-open structure, enabling "blind-access" reloading of five standard rifle magazines-a 60% reduction in access time compared to traditional designs. "Blind access" means the soldier does not need to look down; magazine changes are executed by muscle memory alone-critical in night combat or high-stress environments.

The main compartment features an intelligent partitioning system, where each section uses rigid modules with snap-fit tabs to securely hold equipment of different shapes and sizes.

4.2 Synergy Between the Assault Pack and the Tactical Vest

The assault pack is designed for deep synergy with the tactical vest:

• Independent carry: the assault pack has its own suspension system (shoulder straps + waist belt) and can be used standalone
• Back-panel attachment: can be attached to the vest's rear panel via MOLLE/PALS
• Quick conversion: some products feature rapid conversion between pack and vest configurations

This dual-use mode allows soldiers to choose flexibly-a light assault can be conducted with just the pack, while heavy missions can have the pack attached to the vest for integrated carriage.

5. Sustainment Rucksack: The "Logistics Support Unit" for Modular Storage

If the assault pack answers "how to get it during combat," the sustainment rucksack answers "how to carry it during movement."

5.1 From "Single-Compartment Storage" to "Modular Combination"

Traditional sustainment rucksacks had only a single storage function-one big pocket for everything, requiring rummaging for any item. The new sustainment rucksack completely transforms this model.

The new sustainment rucksack uses a modular storage structure, with each unit independently packaged. When used, they can be combined and secured using buckles, snap-fits, zippers, and hook-and-loop. This design enables soldiers to "adjust on the fly, use immediately" when facing different mission requirements.

5.2 20+ Module Flexible Combinations

The new field sustainment rucksack system mainly comprises more than 20 modules, including the tactical vest, assault pack, sustainment rucksack, forward-deployment bag, and various functional pouches. Soldiers can reconfigure components based on mission type and operational role.

This high level of modularity means:

Long-range marches add high-capacity sustainment modules

Short-range patrols carry only the assault pack and basic pouches

Different branches (infantry, reconnaissance, communications) configure modules according to their speciality needs

6. Synergy and Mission Configuration Logic of the Three Components

The tactical vest, assault pack, and sustainment rucksack are not isolated items - they form a complete individual load-carrying solution. Their configurations vary by mission scenario:

The modular design of the new combat load-carrying system allows soldiers to freely combine "like building with blocks" based on mission type. Whether it is light and fast counter-terrorism in urban environments or heavy-load high-altitude training, rapid switching is achieved on a single unified platform.

7. Lessons and Implications for Tactical Clothing Factories

For tactical clothing factories, the design philosophy of the new combat load-carrying system provides clear product development directions:

7.1 Integrated Protection-Carriage Is the Trend

The convergence of ballistic protection and load carriage into one system is a clear industry trend. When designing tactical vest-type products, factories should consider reserving capacity for ballistic plate insertion-achieving "one vest, two functions."

7.2 MOLLE/PALS is the Standard

The MOLLE/PALS system has become the standard for modular tactical equipment. Any load-carrying product-whether a vest, pack, or pouch-should be compatible with this standard; otherwise, it cannot integrate into the user's existing equipment ecosystem.

7.3 Modularity Is the Core Design Language

The core value of modularity is "on-demand configuration and flexible combination." In product development, factories should consider:

Does the product itself support modular combination?

Can different products interconnect via standardised interfaces?

Can users freely add/remove components based on mission needs?

7.4 Rapid Access Is a Functional Imperative

Whether it is the magnetic quick-open of the assault pack or the quick-release of the tactical vest, the common thread is fast operation under stress. Factories should always treat "access speed" as one of the core design considerations.

8. Frequently Asked Questions (FAQ)

Q: What is the difference between MOLLE and PALS?

A: PALS (Pouch Attachment Ladder System) is the specific technical specification for the webbing grid (1-inch wide, 1-inch spacing). MOLLE is the U.S. military's program name for the system. In daily usage, the terms are used interchangeably, but strictly speaking, PALS is the standard and MOLLE is the system.

Q: How are "integrated protection-carriage" and "modularity" related?

A: "Integrated protection-carriage" is a design philosophy-combining load carriage with protection. "Modularity" is the means of implementation-using standardised interfaces to allow users to freely combine components. The integrated protection-carriage tactical vest itself is part of a modular system and can work in synergy with other modules (assault pack, sustainment rucksack, etc.).

Q: How is flame resistance achieved in the new combat load-carrying system?

A: The new system is made from flame-resistant fabrics, providing good flame resistance. Factories developing similar products can refer to the GB/T 17591 "Flame-resistant fabrics" standard when selecting materials.

Q: Is the "magnetic quick-open" on the assault pack reliable?

A: The magnetic quick-open structure has been refined through hundreds of operational tests and offers reliable performance under normal use. The magnetic closure is designed to balance "rapid opening" with "preventing accidental release."

Conclusion: From single-purpose "bags" to fully integrated platforms combining protection, load carriage, and information integration, the evolution of individual combat load-carrying systems reflects the higher demands modern warfare places on soldier equipment. The tactical vest addresses "how to protect and how to attach," the assault pack addresses "how to access quickly," and the sustainment rucksack addresses "how to carry on the move"-each fulfilling its role, working seamlessly through the MOLLE/PALS standardised interface.

For tactical clothing factories, understanding the design logic of this system means following the three key trends of integrated protection-carriage, modularity, and rapid access in product development. Whether developing tactical vests, tactical packs, or supporting pouches, factories should adhere to MOLLE/PALS standards and incorporate the core concepts of rapid access and modular combination. Understanding the system is the key to designing products that truly meet modern individual soldier needs.
