In 1962, the first USAF custodial unit "Detachment 0600" was activated at Kleine-Brogel to support the 10th Wing.  Detachment 0600 came under the 306th Munitions Maintenance Squadron and was the first American military unit with a combat mission to be assigned to Belgium since the end of World War II.

The unit is a Geographically Separated Unit responsible to receive, store, and maintain US munitions, and to provide custody and control of those munitions until receipt of proper authority to release them to the Belgian Air Force 10th Wing in support of NATO's Strike Mission. These weapons, between 10 and 20 of them (unconfimed), were of the B61 type.  News reports say they will be replaced by the newer B61-12 (unconfirmed).

In July 1964, Det 0600 fell under the 7232nd Munitions Maintenance Group until it became Det. 1 under the 36th Tactical Fighter Wing (Bitburg AB, Germany) in 1967. 

On April 1 1972, Det. 1 was assigned the 7361st Munitions Support Sqn. (MUNSS).  The squadron was transferred to the 52nd Tactical Fighter Wing at Spangdahlem, Germany in July 1976.

In October 1992, the 32nd Fighter Group at Soesterbeg AB in the Netherlands took command as the support base for Kleine-Brogel.

A year later, in October 1993, support reverted back to the 52nd at Spangdahlem.

July 1993 the 7361st was redesignated the 601st MUNSS; to be further designated the 617th MUNSS in July, 1994.

At that time, probably because of some USAF-rule, the name KLEINE-BROGEL disappeared from the patch and was replaced with LEADING THE WAY.

In July 1996 the 52nd Munitions Support Squadron was activated, reflecting direct subordination to the U.S. 52nd Wing under the post-Cold War nuclear weapons regional basing scheme.

It was at that time that the crowned lion of 10 W TAC was replaced with a generic one and the tabs became green.

Currently the 701st MUNSS is charged with safeguarding the ammunition.
