MOLLE (pronounced molly, as in the female name) is an acronym for Modular Lightweight Load-carrying Equipment. 

It is used to define the current generation of load-bearing equipment and rucksacks utilized by a number of NATO armed forces, especially the British Army and the United States Army. The system's modularity is derived from the use of PALS webbing as rows of heavy-duty nylon stitched onto the vest to allow for attachment of various MOLLE-compatible pouches and accessories. This method of attachment has become a de facto standard for modular tactical gear, replacing the ALICE system used in the earliest modular vest systems (which is still in use with many police forces).
