Cpl. Trenton A. Douglass ties a butterfly knot while blindfolded during a tactical rope suspension techniques course Jan. 10 at the Central Training Area near Camp Hansen. Marines had to practice tying basic knots prior to building a one-rope bridge. “You have to be able to properly tie a knot under pressure to ensure that if you need to do it in a moment’s notice to save a life, you can,” said Lance Cpl. Gage L. Theriot. Douglass is a reconnaissance man with 3rd Reconnaissance Battalion, 3rd Marine Division, III MEF. Theriot is a rifleman with 1st Battalion, 3rd Marine Regiment.
