California Army National Guard Staff Sgts. David Ingles, right, and Shelda Mairel, center, of the 118th Maintenance Company, in Stockton, give a class on recovery operations using a M984A1 HEMTT Wrecker at an intermediate staging base at the Sierra College in Rocklin, Jan. 6, 2012, during the 115th Regional Support Group's Emergency Deployment Readiness Exercise, which had 60 vehicles and 217 troops moving their wheeled assets around the state in response to a earthquake scenario. "During operations like these it is critical to have this truck in your arsenal. It is better to have it and don't need it than not having it and needing it," said Ingles, who holds three military skill sets. "This exercise helps keep our skills fresh," said Mairel, who is instructor qualified. "The troop carrier is just as important as any other skill in the military when it comes to supporting a mission like this. Best thing for us is to get out and play like we are doing today."
