Fellow cold warriors will remember the SOXMIS pocket aide memoire which we all carried - big coloured piccie of a SOXMIS vehicle plate, with a prominent number at Herford Mil to 'phone with the report.
This is the form in question.
At Rheindahlen ISTR some fearsome German who examined us for a BFG Driving Licence (the dreaded 'Tick-test') issued these forms to sucessful BFG licence applicants promising dire consequences if we failed to report sighted SOXMIS vehicles.
