The cases include that of Army Maj. Mathew L. Golsteyn, a former Special Forces officer who faces a murder trial in the 2010 death of a suspected Taliban bombmaker; former Special Warfare Operator Chief Edward Gallagher, a Navy SEAL who recently was acquitted of murder but convicted of posing with an Islamic State corpse; and former Army 1st Lt. Clint Lorance, who was convicted of second-degree murder in 2013 and is serving a 19-year prison sentence for ordering his soldiers to open fire on three men in Afghanistan.

Golsteyn faces a court-martial that is scheduled for February. He first came under investigation in 2011 after he applied for a job with the CIA and disclosed during a polygraph test that he had killed someone on deployment and burned the body, according to Army documents and a Washington Post interview with Golsteyn in February.

Golsteyn said he killed the suspected bombmaker in an ambush after he had been detained and crossed paths on base with a tribal elder working with U.S. forces. U.S. troops were required to set the detainee free, he said, prompting fears that he would kill the elder. Golsteyn contends the ambush of the man, who was unarmed at the time, was legal.
