“British officers have said that they do not want to train with large divisions in Porsanger, where the temperature drops to 25 degrees below zero,” said Lt. Col. Trond Thomassen, commander of Norway’s Allied Training Centre in Porsangmoen, told Norwegian-language Finnmarks Dagblad.

“The British have rules for health and safety,” Thomassen told Finnmarks Dagblad, whose article was translated by the English-language Norwegian paper The Local.
