There was always something about the SMG. In the field, many were hung up on tree branch while you took a crap... and subsequently were never found.... searches and SI's were frequent...
Know of one instance where an SMG was lost - our unit was in the same area about 4 wks later -"rusty" weapon chose to show itself.
With a slew of lost weapons over the years; I can understand SIU & MPs jumping to conclusion about the "appearance" of a Cdn pattern SMG. (can also appreceate concept of making MP eat crow / humble pie)
Over the years, have seen a number of Aussie FALs in circulation. I thought it was a better weapon with it's heavier barrel.... and you could use the FNC1 body cover/BB Carrier & Breach block. Always prefered our Body cover VS the small ejection port the standard FAL used.
So back to the SMG - a good improvement over the old STEN "plumbers nightmare"
as with any weapon - dangerous in the hands of an amateur BUT entirely serviceable in the hands of someone who knows what he's doing.... IMHO
