A master sergeant with the 315th Security Forces Squadron at Joint Base Charleston in South Carolina will face a court-martial next month on charges of possession of child pornography.

Master Sgt. Brian Arnold, of the Air Force Reserve, is accused of possessing sexually explicit videos of a minor, or someone who appears to be a minor, between August 2012 and June 2015, according to charge sheet information provided by Joint Base Charleston. If convicted, this would be a violation of Article 134 of the Uniform Code of Military Justice.

Arnold’s court-martial is scheduled to begin March 19 at the base, and end March 23. Maj. Gen. Christopher Bence, the commander of the United States Air Force Expeditionary Center, will be the convening authority.

'Different spanks for different ranks': Lawmaker questions lack of courts-martial for Air Force generals A leading lawmaker has called out the Air Force for never court-martialing a single general officer in its entire history, suggesting it shows higher-ranking airmen face different standards of punishment.

“It is important to remember in the military justice system every individual is presumed innocent until proven guilty beyond a reasonable doubt,” Marvin Krause, a spokesman for Joint Base Charleston, said in an email. “While it is premature to comment on the outcome of the case, charges have been referred to trial by the General Court Martial Convening Authority, and a court will determine if the accused is guilty of the alleged offense and if so, adjudicate an appropriate sentence.”
