Military surplus comes in a variety of different conditions based the three " " rule: What, Where, When.

  • Depending on what the item is will generally determine the amount of use and what it was used for. This is important because some items do not endure the torture of being in the field for prolonged periods of time, while others might.
  1. Ex: Dress Uniforms are not worn in combat, therefore generally, there is lighter use than issued combat/working uniforms.

  • Knowing where the item most likely was issued/stored will generally determine the environment it was exposed to. This is important because some items are exposed to harsher conditions than others, or are straight from storage.
  1. Ex: Uniforms & Gear issued in the Vietnam War saw extreme heat and moister, giving those items specific textures/smells/common problems, while the same items issued to troops in occupied Europe do not have those attributes (Generally better conditions). 
  2. Ex: Uniforms & Gear stored in a controlled environment (warehouses or similar areas) feel and smell different than if it is stored in a non-controlled environment (Random areas/outside/or exposed to elements)

  • Time is a huge factor, when something was issued generally determines the age of the item. As time goes by everything ages, this is the circle of life and it does apply to inanimate objects, like military surplus. Items will show signs of age, typically tarnished metal/fading/stains/rips/holes/rot/smell. The exception to the rule is NOS ( New old stock) items or ones stored carefully in controlled environments.
  1. Ex: Uniforms & Gear from World War 2 are generally made of canvas/leather/twill or HBT fabric, and are close to 100 years old. These items have more than likely seen combat or were reissued in the Korean or Vietnam Wars. Extensive use and the fact that they are almost a century old will reflect the condition & price. This applies to any era. 
  2. Ex: Uniforms & Gear from the original factory box, or items stored carefully in controlled environments will generally retain their durability and "new" look. The age of an item sometimes is not a factor BUT only when it is properly stored or carefully looked after.
