2005

• Marines clashed with a band of insurgents in eastern Afghanistan. The battle began after Marines received a tip about insurgents operating in Laghman, an opium-producing area 60 miles east of Kabul. The insurgents opened fire with small-arms and rocket-propelled grenades before splitting into two groups, one fleeing to a village and the other to a cave on a nearby ridge. The five-hour fight left two Marines and an estimated 23 rebels dead.
• The Marine Corps announced the recall of 5, 277 combat vests issued to Marines in Iraq, Afghanistan, and Djibouti despite insisting the vests provide the ballistic protection they were designed to provide. The recall was to alleviate any doubt about their effectiveness that surfaced after the Marine Corps Times ran an article questioning the quality of the protective gear. The gear recalled represented less than three percent of all vests fielded to date.
• Start of Operation Block Party II in Iraq
