Munition Support Squadrons (MUNS) are geographically separated units which are located over Europe.
Their mission: receiving, storing, maintenance and maintaining custody and control of NATO assigned special USAFE munitions until further notice.
The co-storage of the special weapons together with their strike aircraft greatly enhanced their survivability and operational readiness.
In 2017 Hans M. Kristensen, the director of the Nuclear Information Project with the Federation of American Scientists (FAS) in Washington declared that the numbers of NATO assigned US nuclear weapons in Europe have not been changed since 2009 so it is supposed that they are currently still operational in Turkey, Italy, Germany, Belgium and in the Netherlands.
In 2021, the Pentagon briefly posted a picture of the unit insignia of the 701st Munitions Support Squadron at Kleine Brogel Air Base, Belgium which depicted US and Belgian flags above an eagle clutching a B-61 weapon.
