Loadmaster brings state trooper role to assist in SFS training Published May 29, 2014 By Paul Zadach 934th AW Public Affairs MINNEAPOLIS ST PAUL AIR RESERVE STATION -- Senior Master Sgt. Dean Grothem is usually seen at the 934th wearing his flight suit and working around a C-130 as a loadmaster with the 96th Airlift Squadron. May 29, he showed a different look by rolling up at the 934th Security Forces Squadron in his civilian role as a Minnesota State Trooper. Grothem was there to share his expertise and assist with the SFS DUI recognition training. The training is a combined effort between the 934th AW, 133rd Air National Guard and Minnesota State Patrol to train Security Forces on conducting field sobriety tests and identifying drunk and impaired drivers. During the training several off duty volunteers are given controlled amounts of alcohol and their blood alcohol levels monitored. The volunteers are then subjected to field sobriety tests where Security Forces members are trained in how to recognize signs of impairment and intoxication. Master Sgt. Mike Ross, 934th Security Forces Squadron, said that the training is important in that signs of intoxication must be recognized and probable cause established through the field sobriety test before a breath test or arrest can be made. Grothem enjoys being able to share his civilian training and experience in the field with his military counterparts in the Reserve and Guard. "The training has proven to be a great opportunity to get some hands on training and build a good working relationship between military and civilian law enforcement," he said.
