Golin was originally born in Riga, Latvia, according to an Army press release. He moved to the United States in October 2004 and enlisted in the Army on Jan. 5, 2005.

Golin served in 3rd Battalion, 509th Parachute Infantry Regiment, 4th Infantry Brigade Combat Team (Airborne), at Joint Base Elmendorf-Richardson, Alaska, according to the Army release.

He then volunteered for Special Forces training and graduated from the Army’s Special Forces Qualification Course in November 2014. He was assigned to 10th SFG (A) as a Special Forces weapons sergeant.

Prior to his September 2017 deployment to Afghanistan, Golin participated in three other deployments. He deployed once to Iraq in support of Operation Iraqi Freedom from September 2006 to November 2007, and twice to Afghanistan from February 2009 to February 2010 and from December 2011 to October 2012, both in support of Operation Enduring Freedom, according the Army press release.

Golin’s awards include the Purple Heart Medal with one oak leaf cluster; Army Commendation Medal with two oak leaf clusters; Army Achievement Medal with two oak leaf clusters; Special Forces Tab; Ranger Tab; Combat Infantryman Badge; Expert Infantryman Badge; and the Parachutist Badge, according to the Army release.

The United States formally concluded its combat mission in Afghanistan at the end of 2014 but still carries out operations against the Taliban and an Islamic State affiliate, both of which are active in Nangarhar.

On April 13, the Air Force dropped the most powerful non-nuclear bomb in the U.S. military’s arsenal against the Islamic State in that province. The 21-000-pound GBU-43 Massive Ordnance Air Blast, or MOAB, is nicknamed the “Mother of All Bombs. It was the first ever combat use of the massive ordnance.

Despite the MOAB’s destruction, enemy activity in the province continued.

Two Army Rangers were killed there April 26 in a fierce gun battle with the Islamic State of Iraq and Syria-Khorasan.

Sgt. Joshua “Josh” Rodgers and Sgt. Cameron Thomas of 3rd Battalion, 75th Ranger Regiment, were killed by small-arms fire, according to a Pentagon press release.

In the April incident, about 50 U.S. Army Rangers and 40 Afghan commandos were inserted by helicopter into the Mohmand Valley.

A three-hour firefight ensued, resulting in U.S. special operations forces killing several senior ISIS-K leaders along with about 35 ISIS operatives, U.S. military officials maintain.

A statement at the time from U.S. officials said there was a “possibility” that Rodgers and Thomas were killed by friendly fire and that U.S. Forces Afghanistan is investigating the incident.

Those at the scene report close-quarters fighting and enemy fire coming at them from 360 degrees, U.S. officials said.
