Why is "Pouch Attachment Ladder System" trending?

Wikipedia Overview

The Pouch Attachment Ladder System or PALS is a grid of webbing invented and patented by United States Army Natick Soldier Research, Development and Engineering Center used to attach smaller equipment onto load-bearing platforms, such as vests and backpacks. It was first used on MOLLE rucksacks, but is now found on a variety of tactical equipment, such as the U.S. Improved Outer Tactical Vest, Interceptor body armor, USMC improved load-bearing equipment backpack and Modular Tactical Vest. It is used to attach items such as holsters, magazine pouches, radio pouches, knife sheathes, and other gear. A wide variety of pouches are commercially available, allowing soldiers to customize their kit. There is also a variety of attachment methods including the Alice Clip, the Natick snap, and soft, interwoven straps. The PALS system has begun to be adopted by other forces, such as the British Army, who use it on their Osprey body armor.
