The Kopp-Etchells effect was first documented during combat operations in Afghanistan. The photographer Michael Yon named the effect after two soldiers who died there, Koop, a US Ranger, and Etchells, a British soldier. Both were killed in combat in this province of Afghanistan. Props to the photographer for naming the effect after the soldiers who lost their lives.
