FORT MCCOY, Wis. (AP) – Soldiers and civilians involved in a special training exercise at Fort McCoy are taking extra precautions in the sweltering heat and humidity.  About 2,000 soldiers, airmen and civilian first responders are involved in the National Guard Bureau’s annual Patriot training exercise at the fort, which wraps up Thursday. Participants are training in full firefighting gear and chemical suits.   Wisconsin National Guard spokesman Maj. Paul Rickert says training leaders are pushing water, and as the heat rises during the day more rest time is added in between exercises. Rickert says a couple soldiers have been treated on site for heat exhaustion.  Rickert says dealing with the heat is something familiar to military members. Rickert says it was 140 degrees during his deployment in Iraq.
