Are there any known examples of documents/materials of how any police/military organization may have trained/use/care on the few MACs that entered into some service roles?
I understand many were not sold or used in regular roles - however it seems plausible that given the organizations that did buy them some entity may have documented or developed some training docs for its use.
Perhaps some Police agency or the US Navy SEALs may have tried these enough to determine it may take some specialized handling to get the most out of it and documented some techniques, etc.
On the other hand I can see that possibly
-Some agencies and buyers didn't want documentation of use - used for clandestine purposes.
and/or
-its limited utility may have lent itself to buyers remorse where purchases went as evaluation items that went undeveloped and undocumented.
My interest is out of collectors/historical interest and have not found much out there and hope the collecting community might offer more.
Thanks up front for those that might offer some info.
