is an item of ammunition that when fired, thrown, dropped, projected or used fails to function at all. This results in an item that may have all of the normal safety restraints that prevent functioning removed or partially removed. As such often it cannot be discerned what state it is in and so is assumed to be at its most dangerous. Blinds are particularly angry items and definately come under the catagory, 'If someting bad can happen - it will!'. The item can be low or high explosive, designed to explode or create some pyrotechnic effect (such as smoke or Illuminating) all can become a blind. Other useful descriptions, if it functions but not completely it is a Partial,
and if it functions but not as intended it is a Performance Failure.
The last museum I did was a Regimental one in the South of England (name withheld to protect the hoarders
) and took me 4 days and two bomb vans full of live stuff. The DOVO are good people, so are the Demineur. I have many friends in both and regularly visit to keep up contact and swap ideas. EOD is a small world and we don't keep good ideas to ourselves to the detrement of others.
Hope this helps. Please let meknow if you want any further ellaboration?
