Battalion 3/5 suffered the highest number of casualties in the war in Afghanistan. This is the story of one platoon in that distinguished battalion.  Aware of U.S. plans to withdraw from the country, knowing their efforts were only a footprint in the sand, the fifty Marines of 3rd Platoon fought in Sangin, the most dangerous district in all of Afghanistan. So heavy were the casualties that the Secretary of Defense offered to pull the Marines out. Instead, they pushed forward. Each Marine in 3rd Platoon patrolled two and a half miles a day for six months—a total of one million steps—in search of a ghostlike enemy that struck without warning. Why did the Marines attack and attack, day after day?     Every day brought a new skirmish.
