The most common tourniquet in use today within the worlds military. It is one of the best, lightest and simplest to use of its type. It is easy to apply and allows the operator to apply controlled circumferential pressure to a limb in the presence of a severe arterial bleed. This means that only enough constriction to stop the bleeding needs to be applied making it less dangerous than other non-controllable tourniquets.
Its design means that it can be carried in a pocket or pouch while taking up minimal space.
