Cpl. Yao Lee, Installation Personnel Administration Center pay administration clerk, hauls himself out of the Oasis Pool at the Marine Corps Air Station in Yuma, Ariz., during his Marine Combat Water Survival Course qualification, Jan. 28, 2010. Seventeen Headquarters and Headquarters Squadron Marines braved the approximately 50 degree water to qualify for the initial level of swim qualification, while Lee and two other Marines continued to the third level of qualification. The third level requires Marines to enter the pool with a combat load and simulated rifle, swim 50 meters, and then tow a simulated casualty 25 meters through the water. Qualifications, which are usually held at Naval Air Facility El Centro, Calif., for Yuma Marines, have been held on station for approximately a month due to the expense of transporting Marines there. “I don’t think the training is as realistic here,” said Cpl. Nick Wolff, H&HS Marine combat water survival instructor, referring to Oasis Pool’s lack of a high dive. “But you’ve got to do what you’ve go to do to get the mission accomplished."
