As part of a month long newly implemented Integrated Training Exercise, Marines from Marine Aircraft Group 13 based out of Marine Corps Air Station Yuma, Ariz. participated in a day-long Team Warrior Challenge competition at Marine Corps Air Ground Combat Center Twentynine Palms, Calif., Jan. 25. "The course itself is .4 miles, which is less than the movement to contact sprint on the CFT,” said SSgt. Aaron McCatty, a Marine Aircraft Group 13 Headquarters chemical biological radiological nuclear defense specialist and a native of Tampa, Fl.
