It’s not a monument or an elaborate fundraiser, just a personal journey of remembrance.

As the 30th anniversary of the deadly Oct. 23, 1983, bombings in Beirut, Lebanon, draws close, former Marine sergeant Paul “Doc” Doolittle is preparing to embark on a 273-mile walk in honor of the peacekeeping Americans killed in the attack. In all, 220 Marines and 21 other U.S. service members were killed when terrorists drove trucks laden with explosives into their barracks buildings.

Doolittle was stationed in Beirut as an embassy security guard in July 1985, shortly after the barracks attack and two separate bombings of U.S. embassy buildings in 1983 and 1984. [Link]
