Cold water acclimation exercises are an important part of water operations for Mountain Division and K9 TZ operators. That's why Teame members take time to get out and about in glacier-cold water and practice staying out of the water.
Sudden immersion in cold water can cause physiological reactions that can overcome mental focus and substantially increase the risk of drowning. Working with K9 units in near-freezing conditions means planning and taking deliberative action.
