re: Retired Green Beret officer: Mattis "left my men to die."

What a bunch of bullshite. They fail to mention that the incident that Mattis "failed" to support was a spec-ops, CIA operation. The Marines are quite removed from such missions, especially in 2001 (it's much more integrated now). They also don't mention what the Marines were in the middle of doing when this situation came up. I read a good book related to this incident, but more focused on the CIA's operations leading up to and during the invasion of Afghanistan. Those guys had their own support system and were quite outside the Marine's scope of responsibility.
