One of the tasks of an infantryman in a unit is to provide accurate and long-term fire to suppress or destroy enemy personnel, to ensure this, the soldier must have a lot of pouches to accommodate additional ammunition.   

The "MP-101" pouch is designed to accommodate one or two magazines for the M4 carbine or as VAL, similar to them or similar in size. It closes with a Velcro flap and is equipped with a elastic band.   

The pouch can be used either by closing the flap or by removing it inside - in this case, the magazine is fixed with a tightening elastic band.
