Greenland's elite Sirius Dogsled Patrol, a Danish navy unit, conducted patrols across desolate icy Arctic terrain during the 3-hour reporting window from 3:45 AM to 6:45 AM UTC on January 29, 2026. President Donald Trump ridiculed Denmark's defense of Greenland as limited to 'two dogsleds,' according to an AFP report published in this period. The Sirius Dogsled Patrol works in extreme conditions where only the toughest survive, countering Trump's characterization, as stated in the AFP article shared on X at an unspecified time within the window. The unit patrols areas inaccessible by other means. No additional operational details or official statements from Danish or Greenlandic authorities emerged during this 3-hour period, per the sole sourced report.
