GREAT FALLS, Mont. -

Montana will be the site of a large training exercise next week as military officials prepare for the worst of all fears: An attack on nuclear facilities.
    
Personnel at Malmstrom Air Force Base near Great Falls regularly test how they'd respond to such an incident.
    
But the Great Falls Tribune (http://tinyurl.com/cxm2db3 ) reports that starting Monday, Malmstrom and Fort Harrison in Helena will be the focus of a national exercise including about 1,000 people.
    
Some local and state first-responders will also be involved, to make sure the link between military and civilians is robust.
    
If something bad happens, "we want to kind of go on autopilot," says Col. Rob Stanley, 341st missile wing commander at Malmstrom.
    
Locals may notice a bit more traffic, including helicopter activity and people wearing hazmat suits.
