Interior Ministry spokesman Markus Amman said nobody in Liechtenstein had even noticed the soldiers, who were carrying assault rifles but no ammunition. "It's not like they stormed over here with attack helicopters or something," he said.
Liechtenstein, which has about 34,000 inhabitants and is slightly smaller than Washington, D.C., does not have an army.
Eh, it's the freakin Swiss. If you see a Swiss soldier anywhere outside the land of great chocolate, you know he made a wrong turn somewhere. It's not exactly like they have a recent history of hostile intentions. "Hey, we're neutral and scary! I dare ya to stick your toe over our border again!"
(Note, do NOT stick toe over border with hostile intend. It's a crime not to keep your govt supplied assault rifle in your home, with a minimum of 50 rds of ammo.)
