XCTC is one of the largest National Guard training exercises of the summer. Slightly more than 3,000 155 mm howitzer rounds and 192 High-Mobility Artillery Rocket System rockets were expended. More than 200,000 blank firing ammunition were issued and 300 mortar rounds were fired. "The 197th was selected as the first field artillery brigade to go through this training," said Spencer. "We're the first brigade to conduct this type of exercise at Camp Grayling. And, this is the first unit to incorporate an active duty portion."
