Having spent my life as a foreign (German) national in the most neutral and peaceful country in Europe (Switzerland) I did not serve and I have no affiliation with LE.
However having read this entire thread is really interesting and like others, I wish to express my appreciation for those who put themselves on the line to protect the others.
I’ve had the pleasure of collecting and shooting some of the weapons mentioned and if I may, I post a few pics for illustration.
