To facilitate the easy attachment of equipment, the United States Army developed the PALS - Pouch Attachment Ladder System, sometimes incorrectly referred to as MOLLE. This system consists of horizontally sewn straps, each 1 inch (2.54 cm) wide, with a vertical spacing of 1 inch as well. The straps are sewn onto the base fabric with a spacing of 1.5 inches. It is most commonly used on backpacks and vests. Equipment components, typically various pouches, are attached to the PALS webbing by weaving their straps with buckles through the supporting straps.
The disadvantage of the PALS system is the inability to attach equipment horizontally. Although this can be circumvented by using a special adapter, it does complicate matters. This issue was addressed by the German Army, but the solution is not entirely compatible with the original American system, which can be problematic during international operations.
The ALP company developed its own webbing system composed of both horizontal and vertical straps, each 2.54 cm wide. These straps are sewn onto the base fabric at precise intervals, creating a field of 2.60 cm along the entire length of the horizontal strap. On the vertical straps, the same field is formed between every two horizontal straps. This system allows the placement of pouches both vertically and horizontally. At the same time, it remains fully compatible with the PALS system. Another advantage of the ALP Type I universal webbing is the possibility of 100% utilization of the area of the horizontal straps, allowing pouches to be attached closely together. Thanks to the tighter attachment of pouches to the carrier, the pouches move less during running.
While the Universal Webbing ALP Type I is a very good solution for the modularity of a soldier's equipment, there remained some room for improvement. There was a search for a way to allow not only 100% utilization of horizontal straps but also 100% utilization of vertical straps. The solution turned out to be a new method of sewing straps that allowed for 100% utilization of strap length, enabling much more precise placement of pouches, no matter how they are turned at an angle of 90 degrees. The new universal cross webbing consists of horizontal straps 2.54 cm wide, which are placed first. Over them, narrower vertical straps are sewn. Passages for threading the pouch straps are therefore along the entire length of both horizontal and vertical straps. Full compatibility with the PALS system has been maintained. The new system, for example, allows for the use of both front and rear surfaces of a ballistic vest according to individual needs, as the user can place and rotate pouches exactly for convenient reach.
