I have posted many stories about the accomplishments of 2/7 Marines, and have interviewed their Battalion Commander several times and even emailed with him personally. This story in the LA Times does a good job summarizing some of the obstacles and combat hardships they faced.
The Marines of the Two-Seven were not even supposed to deploy to Afghanistan. Their original destination was Iraq, and when they were sent here in April as a stopgap measure to help an overwhelmed NATO force, the plan had been to spend the time mentoring Afghan national police.
It didn’t turn out that way. Instead of training policemen, the lightly equipped 2nd Battalion, 7th Regiment of the 1st Marine Division found itself engaged in firefights with insurgent units of 100 or more fighters. They faced Taliban snipers and roadside bombs.
Twenty members of the 1,000-member battalion died in combat.
