In 1985 the Swiss Army fired off shells during an exercise and mistakenly burned a patch of forest inside Liechtenstein. The incident was said to have been resolved "over a case of white wine". In March 2007, a 170-man Swiss infantry unit got lost during a training exercise and inadvertently crossed 1.5 km (0.9 miles) into Liechtenstein. The accidental invasion ended when the unit realized their mistake and turned back.The Swiss Army later informed Liechtenstein of the incursion and offered official apologies, to which an internal ministry spokesperson responded, "No problem, these things happen."
