POMCUS (Prepositioning Of Materiel Configured in Unit Sets) was a system that kept large amounts of pre-positioned U.S. military equipment in West Germany during the Cold War.
[1] In the event of war with the Soviets, American soldiers could be flown with their "to-accompany-troops" (TAT) gear on Civil Reserve Air Fleet commercial airliners to use this pre-positioned equipment.
The equipment was set up in unit configurations to aid in force building and movement to support the US Army's general defensive plan (GDP).
When the Berlin Wall fell, and the Soviet Union no longer existed, plans were then cut back severely and sites that were considered in the Benelux were cancelled.
Originally, POMCUS sites were primarily simply guarded, fenced-in lots of pre-loaded, maintained vehicles and weapons systems ready to roll, although the precursor to POMCUS sites was a series of underground storage areas taken from the Germans in Pirmasens and the outlying areas Husterhoeh Kaserne utilised to store combat-readied armour.
