In this 2009 file photo from Iraq, Lance Cpl. Zachary Taylor, a landing support specialist with Combat Logistics Battalion 7, touches a static wand to a cargo hook hanging from a CH-53E Super Stallion to ground the aircraft and eliminate the hazard of static electric shock. To prevent electrocution, Marines on the ground do not touch the aircraft until it has been grounded.

At least four Marines have been electrocuted in separate incidents since November while serving in Afghanistan, according to the Marine Corps Times.

Their deaths were caused by low-hanging power lines that touched radio antenna and problems stemming from an electric generator, the Times reported, citing documents the paper obtained through a Freedom of Information Act request.

The Marine Corps Times reported those electrocuted in Afghanistan recently are Cpls. Adam Buyes, Connor Lowry and Jon-Luke Bateman and Lance Cpl. Kenneth Cochran.
