They are wrong about orders not being sent to a Guardman's home address. Where else would they send them. It's not like he's in the squadron office, or even on the base, every day. All my orders as a reservist and guardsman came to my house.
Thank you for the information. Others have also said they thought these were different documents.
I still think that there may be a connexion. May-be it's the same people hawking them, or may-be one inspired the other.
