A Term given to those people who are collectors, Who Enjoy Collection Military Goods or Hoarders, Who collect military goods and other items thinking they'll be of some use for when the time comes.

These types of people get their goods from surplus stores, the internet, miltary swap meets or collecting stuff from their time in miltary.

These people can tend to drive around all terrain vehicles from restored M715's to driving about in a modified post- apocalypitic styled 4WD with Miltiary Jerry Cans and Mermite food containers in the back.

These people can be veterans, crazy buggers or just people who think the stuff is neat.

If you ask nicely they might let you play with their WMD around in the backyard shed or just gouge your eyes out with their bayonet for seeing too much.
