The British forces MTP 40mm rank slide tab is a medium sized loop of MTP printed 40mm webbing tape as used on the front of the MTP Osprey vest that loops together and is held fast with a press stud. The length of the loop is 125mm, so as to around three of the 25mm wide MOLLE straps attached to the Osprey. The purpose of the rank slide tab is to provide a removable vertical loop for attachment of a rank slide or similarly shaped item. It can also be used to provide a quickly detachable point on the MOLLE base for small utilities. Made of IRR Milspec Cordura.
