Two Utah peace officers have been suspended without pay over a risque video shoot featuring bikini-clad women firing high-powered weapons.

The Utah Department of Public Safety imposed the discipline in December on Rob Wilkinson, a Utah Highway Patrol sergeant, and Justin Hansen, a State Bureau of Investigation agent. The department released its discipline records last week after receiving a request to obtain them by The Salt Lake Tribune.

Wilkinson, who received a three-day suspension, and Hansen, who received a one-day suspension, were at the Big Shot Ranch near Grantsville in June when British bikini models posed for photos and were videotaped firing guns for a calendar called "Hot Shots."

The two men were seen wearing camouflage uniforms identifying them as police in a promotional video posted on YouTube in October.

Neither Wilkinson nor Hansen sought their superiors' permission to participate, and superiors learned of the activity only when they saw video clips played by the news media in Utah, according to the records.

The men were disciplined for conduct that brings discredit to an officer or agency, and for wearing their uniform during a promotion for a product — both rules violations, the records show. Wilkinson and Hansen declined comment.

An acquaintance asked the two to help supervise the firing line where the models shot at targets, according to an internal affairs report. The report also notes Hot Shots purports to donate a portion of its proceeds to charities for wounded soldiers.

In November, four Utah National Guard soldiers were disciplined for their unauthorized involvement and use of military vehicles in a video featuring the bikini-clad women firing high-powered weapons and riding in tanks.

A non-commissioned officer who inappropriately allowed the video to be partially shot at Camp Williams in May was relieved of his duties, and three other soldiers received lesser measures ranging from counseling to a reprimand.
