Suited up Guardian Challenge competitors go through a make-shift lab at the Warrior Training Center June 5 during CBRNE Response Team challenges in an effort to become the top CRT. "Once they put on the suit it's a whole different ball game," said Sgt. Kellie Anderson, an evaluator during this portion of the competition. She said wearing the gear may make the Soldiers feel confined and constricted, add to a higher stress level and present dexterity issues. But CRT members must overcome those issues since they may have to wear the suits for long stretches of time during missions.
