A Greyshirt could be stood down for a couple of reasons: 

  1. We didn't receive a response to our reconfirmation email in the required amount of time. 
    • No response to re-confirmation emails is treated as withdrawal from consideration for an operation.
  2. The operational needs changed. Examples include:
    • Less Greyshirts are required for an operation.
    • Scope type has changed. 
    • Amount of work has reduced.
