This was taken at one of our gredadier training sessions at Navajo Army Depot.  Grenadiers are part of the Civil Emergency Task Force (CETF) and are trained in the use of less than leathal tactics.  Officers are trained to use tear gas, wooden and rubber baton rounds, rubber pellets and 12 gauge bean bag rounds as an alternative to using deadly force or in crowd control.  This is becoming a more popular resource of enforcement and much needed.  In light of recent events, there are a select few who can't even celebrate a sporting event without getting out of hand.  It is sad to see people who take advantage of such events just to ruin it for law abiding citizens.
