AttackPAK Integrated Load Carriage System (ILCS)

AttackPAK has been issued 2 patents for their Integrated Load Carriage System (ILCS). The system is designed to unburden the soldier by integrating armor, fighting, and sustainment loads into one-system, with a universal chassis. The design is based on an independent waist belt and frame for optimum load distribution, which also doesn’t restrict range of motion or agility.

This is a simple and robust design that has no moving parts to break. It can be worn connected or disconnected, inside of body armor, over body armor, or without body armor, to adapt to every user. The AttackPAK is easy to ditch in an emergency and can be donned without assistance.

The frame and belt provide an ergonomic fit for each user. Three different model belts are available to carry more or less weight. The AttackPAK system can utilize suspenders to transfer weight between the hips and shoulders to reduce fatigue. The packs are modular and scalable to adapt to changing missions.

The AttackPAK is a complete solution, designed from the ground up, to eliminate redundancy and the “Christmas tree” effect. The resulting system eliminates 2+ pounds from currently fielded equipment.

Lessons learned, Afghanistan and Iraq:
Soldiers need body armor or plate carriers that more comfortably facilitates a heavy rucksack.

In 2016 the US Soldier Enhancement Program purchased 60 demonstration units for testing and evaluation. This purchase followed AttackPAK’s response to SPD9 in 2011.

PAK has been designing, building, and repairing backpacks for over 30 years. His years of Mountain Rescue and high-altitude ski patroller service gave him the real-world testing opportunities. His lifelong friend retired from NSWDG after 20 years and complained about constant back pain from carrying heavy equipment with ineffective gear. That friend’s Tier 1 military expertise, combined with mountaineering pack comfort, helped create the AttackPAK, a new system designed to eliminate the “suck” and provide greater soldier safety.

The AttackPAK design is beneficial for backcountry hikers, mountaineers, rescuer workers, as well as military, law enforcement, and wildland firefighters. The products can be seen at
