OTAN soldiers have employed ALICE system for more than 30 years. Despite its success, there was a common complaint: the troubles to quickly attach accesories.
The main idea is that an infantry soldier loads the minimum required for the mission.That's why ALICE has a set of suspenders and belts forming a joint of the belt, backpack and suspenders to light weight up.
After many dismissed drafts, PALS (Pouch Attachment Ladder System) saw the light in the '90s. A system of belting and nylon straps of about 2,5mm wide, suitable to be attached to any compatible equipment.
In spite of the commercial denomination PALS, the whole set started to be called MOLLE (Modular Lightweight Load-Carrying Equipment). From that moment, both basic panel and straps began to be called MOLLE o MOLLE compatible.
