KODIAK, Alaska (April 8, 2009) A SEAL Qualification Training candidate looks out from a two-man tent during a re-warming exercise in which he spent five minutes in near freezing water. Candidates completed the re-warming exercise after spending 48 hours in the Alaskan mountains learning how to navigate through the rugged terrain and survive the frigid conditions. The 28-day cold-weather training course, taught in Kodiak, is part of a yearlong process to become a US Navy SEAL. (US Navy Photo by Mass Communication Specialist 2nd Class Erika N.
