Would have to see more context, but from what you posted, sounds like this could be it:

http://en.wikipedia.org/wiki/War_Reserve_Stock

A War Reserve Stock (WRS) is a collection of warfighting material held in reserve in pre-positioned storage to be used if needed in wartime. They may be located strategically depending on where it is believed they will be needed. In addition to military equipment, a war reserve stock may include raw materials that might become scarce during wartime. According to this definition, storage such as the Strategic Petroleum Reserve may be considered a war stock.

The United States maintains war reserve stocks around the world, mainly in NATO countries and in some major non-NATO allies. The US 31st Munitions Squadron is tasked with maintaining and distributing the largest war reserve stock piles of munitions for the United States Air Forces in Europe.
