Is the military shotgun an american thing?

[k9870]

I don't see any foreighn countries issuing shotguns to military forces. I look through history and it seems just america uses it. The germans even tried o have shottys banned. We issue the m1014, 870, 590 and 1300. Close quarters, breaching, lots of uses. Why does it seem nobody else really warmed up to the shotgun.?
